Summary

TLDRThe video ranks 20 popular quad exercises from best (S-tier) to worst (F-tier) based on quad tension during stretch, comfort, and progression. Key exercises include squats and leg presses. The barbell back squat, despite minor concerns about rectus femoris activation, remains in S-tier, illustrating its effective tension delivery when performed deeply. The hack squat, praised for efficiency and minimal setup, is crowned the best. Contrarily, bosu ball squats are criticized for instability, placing them in F-tier. Front squats, although more quad-focused, lose points for perceived discomfort, while smith machine squats and 45° leg presses are recognized for their hypertrophy potential, ranking accordingly. Exercises like leg extensions, reverse Nordics, and goblet squats are recommended based on available equipment and user comfort, ensuring options for targeted muscle growth. The video emphasizes technique and comfort to maximize quad development, highlighting practical considerations and common misconceptions, such as myths surrounding knee safety with leg extensions.

Takeaways

  • 🏋️‍♂️ Hack squat is the best quad exercise for muscle growth.
  • ❌ Bosu ball squats are inefficient due to instability.
  • 🔥 Barbell back squats provide exceptional quad tension and overload potential.
  • 👌 Leg extensions are safe for knees and effectively engage all quad heads.
  • 💪 Bulgarian split squats deliver high quad engagement with notable soreness.
  • 📏 Front squats shift more tension to quads but may feel uncomfortable.
  • 💥 Deadlifts are less effective for quads compared to other exercises.
  • 🚀 Progressive overload is key for muscle growth in quad exercises.
  • ✅ Goblet squats suit beginners learning squat form.
  • 🐾 Rectus femoris activation is balanced with varied exercises.

Timeline

  • 00:00:00 - 00:05:00

    The video ranks quad exercises from best to worst for muscle growth, using a tier system from S (super) to F (fail). An S-tier exercise should have high quad tension, especially in the stretched position, be comfortable without causing knee pain, and allow for simple progression. The anatomy of the quadriceps, composed of four heads, is explained, and it is noted that all quad exercises involve knee extension while the rectus femoris also performs hip flexion. Combination exercises like squat plus press are criticized for their inefficiency and placed in F tier. The barbell back squat is praised for fulfilling the S-tier criteria and noted to have high tension on quads and potential for progressive overload. The barbell front squat is similar but shifts even more tension to the quads due to posture changes, earning it an A tier despite some discomfort in execution. Low bar back squats, although transferring some tension to glutes, still ensure high quad activity and are rated similarly. The hack squat offers benefits of barbell squats with added stability and is highly praised, along with pendulum and Smith machine squats, earning S-tier status.

  • 00:05:00 - 00:12:21

    Upper body limitations and instability are common reasons exercises are rated poorly in the video, while high tension, comfort, and overload capabilities are praised. The leg press is valued for quad tension though the horizontal leg press and depth issues lower its tier due to limited overload potential. Lunges are seen primarily as a glute exercise, rated lower for quads, while leg extensions effectively engage all quad heads and are placed in A tier. The reverse Nordic is accessible and provides a deep stretch but is challenging to overload, earning it an A tier. Exercises like goblet squats face limitations in overload potential. Jump squats are criticized for muscle building, placed in F tier, while Bulgarian split squats are deemed highly effective for muscle imbalance corrections and soreness, rated in S tier. The video emphasizes effective muscle activators over those more suited for calorie burning or strength building. The hack squat is crowned the best exercise due to its balance of tension and accessibility, while the bosu ball squat is labeled the worst due to instability.

Mind Map

Video Q&A

  • What criteria determine the ranking of quad exercises in the video?

    Exercises are ranked based on quad tension, especially during stretch, comfort (e.g., lack of knee pain), and ease of progression.

  • Why are bosu ball squats considered the worst quad exercise?

    Bosu ball squats are unstable, diverting stabilization to the ankles, which reduces quad tension.

  • Which quad exercise is crowned as the best according to the video?

    The hack squat is crowned as the best quad exercise.

  • Is the barbell back squat considered effective for quad growth?

    Yes, it provides high tension and Progressive overload, although it slightly under-activates the rectus femoris.

  • Why might some people prefer the barbell front squat over the back squat?

    The front squat shifts more tension to the quads, but might be perceived as uncomfortable by some due to posture requirements.

  • Are leg extensions bad for your knees?

    The video debunks the myth that leg extensions are bad for knees, noting their effectiveness in engaging all quad heads.

  • How do deadlifts rank as a quad exercise?

    Deadlifts rank lower because they don't engage the quads as much as other exercises but are better for glute growth.

  • What is a recommended alternative if hacks squats are unavailable in the gym?

    A high bar barbell back squat is recommended if hack squats are unavailable.

  • Does the video mention any exercises that are particularly good for beginners?

    Goblet squats are recommended for beginners to learn squat mechanics.

  • Is muscle soreness an indicator of hypertrophy according to the video?

    While not a perfect indicator, soreness in exercises like Bulgarian split squats hints at effective muscle targeting.

    what are the best and worst quad
  • 00:00:01
    exercises for muscle growth well in this
  • 00:00:03
    video I'll be ranking 20 of the most
  • 00:00:05
    popular movements on a tier list from s
  • 00:00:08
    for super to F for fail and at the end
  • 00:00:11
    I'll Crown one exercise as the best of
  • 00:00:13
    the best and one as the worst of the
  • 00:00:15
    worst and for a quad exercise to get
  • 00:00:17
    into s tier it needs to tick three boxes
  • 00:00:20
    first High quad tension especially in
  • 00:00:23
    the stretched position second it needs
  • 00:00:25
    to feel good that means it doesn't cause
  • 00:00:27
    knee pain and it has a smooth resistance
  • 00:00:29
    profile third it needs to have a simple
  • 00:00:31
    progression that means you can apply
  • 00:00:33
    Progressive overload by either adding
  • 00:00:35
    some weight or a rep from week to week
  • 00:00:37
    now as I'm sure you all know there are
  • 00:00:39
    four heads of the quadriceps hence the
  • 00:00:41
    quad prefects actually one recent
  • 00:00:43
    Anatomy paper suggested that there could
  • 00:00:45
    be a fifth head but if it does exist in
  • 00:00:47
    some of us I don't think it changes
  • 00:00:48
    anything training wise the foreheads are
  • 00:00:50
    the vastest medialis also known as the
  • 00:00:52
    teardrop muscle on the inside the
  • 00:00:55
    vastest intermedius which runs down the
  • 00:00:57
    middle the vastest lateralis on the
  • 00:00:59
    outside and finally there's the rectus
  • 00:01:01
    femoris which is a long flat head that
  • 00:01:03
    also runs down the middle on top of the
  • 00:01:06
    other heads all four heads contract to
  • 00:01:08
    perform knee extension which is when you
  • 00:01:10
    straighten your knee out so every
  • 00:01:11
    exercise we cover performs knee
  • 00:01:13
    extension however one head that long
  • 00:01:16
    flat rectus femoris has a second
  • 00:01:18
    function it also performs something
  • 00:01:20
    called hip flexion which is when you
  • 00:01:21
    raise your leg up to the front keep this
  • 00:01:23
    in mind for later all right let's get
  • 00:01:25
    the worst out of the way so you guys
  • 00:01:26
    don't waste any time on them let's see
  • 00:01:28
    squat combination exercises like the the
  • 00:01:30
    squat plus press and the lunge plus curl
  • 00:01:32
    are going straight to F tier that's
  • 00:01:34
    because your quads are way stronger than
  • 00:01:35
    your shoulders or your arms so your
  • 00:01:37
    upper body is always going to fatigue
  • 00:01:39
    well before your quads bosu ball squats
  • 00:01:41
    are so bad I didn't even film them the
  • 00:01:43
    problem is because they're so unstable
  • 00:01:45
    your ankle ends up doing a lot of the
  • 00:01:46
    stabilization work and that severely
  • 00:01:48
    limits the amount of tension that your
  • 00:01:50
    quads receive they might have some
  • 00:01:51
    utility in some athletic contexts but
  • 00:01:53
    for building muscle bosu ball squats are
  • 00:01:56
    going straight to F tier all right so
  • 00:01:57
    what about the most popular quad
  • 00:01:59
    exercise of all time the barbell back
  • 00:02:01
    squat well let's see it offers high
  • 00:02:04
    tension on the quads deep in the hole
  • 00:02:06
    when they're most stretched they should
  • 00:02:07
    feel good especially once you lock in
  • 00:02:09
    your bar path and they might be one of
  • 00:02:10
    the best exercises for Progressive
  • 00:02:12
    overload period you can always add a
  • 00:02:14
    little weight or a rep each week as you
  • 00:02:16
    gain size and strength now because it's
  • 00:02:17
    a free weight squat your spinal Erectors
  • 00:02:19
    will have to do some stabilization but
  • 00:02:21
    that's not a deal breaker in my opinion
  • 00:02:23
    your quads are still the prime movers
  • 00:02:25
    and if you need any proof that squats
  • 00:02:26
    can build some monster quads just go to
  • 00:02:28
    a powerlifting meat all the biggest
  • 00:02:30
    squatters will have some massive quads
  • 00:02:32
    and I don't think I've ever seen an
  • 00:02:33
    exception to that now some Anatomy
  • 00:02:35
    enjoyers will point out that the rectus
  • 00:02:37
    fous head is not maximally activated by
  • 00:02:39
    the squat because unlike the other three
  • 00:02:41
    heads it's shortening at the knee while
  • 00:02:44
    lengthening at the hip this is true
  • 00:02:46
    however studies still show pretty solid
  • 00:02:48
    rectus femoris growth with squats and as
  • 00:02:50
    long as you include one other exercise
  • 00:02:52
    in your program that will get to this
  • 00:02:54
    concern completely goes away so while
  • 00:02:56
    the mild Anatomy concern almost pulls it
  • 00:02:58
    back to a tier I just can't take the
  • 00:03:00
    barbell back squat out of s tier without
  • 00:03:02
    a guilty conscience the barbell front
  • 00:03:04
    squat has all the same upsides of the
  • 00:03:06
    barbell back squat except it actually
  • 00:03:08
    shifts even more tension to the quads
  • 00:03:10
    that's because where the barbell Center
  • 00:03:11
    of mass is shifted forward in front of
  • 00:03:13
    your neck you're forced to keep a more
  • 00:03:15
    upright posture so you don't fall over
  • 00:03:17
    this increases the moment arm to the
  • 00:03:19
    knee joint placing more tension on the
  • 00:03:21
    quads that said the forward bar Position
  • 00:03:23
    will also force your upper back to work
  • 00:03:25
    harder and some coaches argue that this
  • 00:03:27
    causes your upper back to become the
  • 00:03:28
    limiting factor I don't fully agree
  • 00:03:30
    unless you're going super heavy you
  • 00:03:32
    really should be able to keep your
  • 00:03:33
    elbows up and you should be able to get
  • 00:03:35
    your quads close to failure without your
  • 00:03:37
    back giving out first now front squats
  • 00:03:38
    will lose a few points in the feels good
  • 00:03:40
    department for some of you but remember
  • 00:03:42
    that for bodybuilding you can use the
  • 00:03:44
    two-finger grip the crossed arm grip or
  • 00:03:46
    the strap grip whatever feels best from
  • 00:03:49
    there just focus on keeping your elbows
  • 00:03:50
    up squatting down between your legs and
  • 00:03:52
    standing back up with a tall chest I'm
  • 00:03:54
    going to put these in a tier because
  • 00:03:56
    despite activating the quads a bit more
  • 00:03:58
    I find enough people just hate doing
  • 00:04:00
    them or find the bar position awkward
  • 00:04:02
    and I don't think there's enough of a
  • 00:04:03
    tension shift to Trump that if you can
  • 00:04:05
    do them comfortably though I'd have no
  • 00:04:06
    problem if you bump them up to S tier
  • 00:04:08
    Okay so we've covered a high bar back
  • 00:04:09
    squat in a front squat what about a low
  • 00:04:12
    bar back squat for a low bar squat you
  • 00:04:14
    shift the barbell Down 2 or 3 in so it
  • 00:04:17
    sits on your rear delts instead of your
  • 00:04:18
    upper traps and research shows that
  • 00:04:20
    while this technique will allow you to
  • 00:04:22
    load more total weight it actually
  • 00:04:23
    shifts some of the tension away from
  • 00:04:25
    your quads and onto your glutes this
  • 00:04:27
    isn't a complete deal breaker though
  • 00:04:29
    because you you still see extremely high
  • 00:04:30
    quad activity as long as you're
  • 00:04:32
    squatting to a reasonable depth low
  • 00:04:33
    breath squats are going in a tier as
  • 00:04:35
    well the hack squat is a longtime
  • 00:04:37
    bodybuilding staple and it ticks all the
  • 00:04:38
    same boxes as the barbell squat plus it
  • 00:04:41
    has a few extra benefits you can
  • 00:04:42
    generally get your sets done a bit
  • 00:04:43
    faster because there's less setup you'll
  • 00:04:45
    be a bit more locked in meaning less
  • 00:04:47
    stabilization work and potentially more
  • 00:04:49
    direct quad tension and you can play
  • 00:04:51
    with your foot position to find a
  • 00:04:52
    comfortable spot without worrying about
  • 00:04:54
    your balance contrary to popular belief
  • 00:04:56
    the latest science shows that on average
  • 00:04:58
    free weights and machines can both build
  • 00:05:00
    muscle roughly equally as long as you're
  • 00:05:02
    pushing your sets hard this is truly a
  • 00:05:04
    brilliant quad Builder and it's
  • 00:05:06
    obviously going an S TI the pendulum
  • 00:05:08
    squat is similar to the hack squat
  • 00:05:09
    except the weight moves up and down in
  • 00:05:11
    an arc I actually find this resistance
  • 00:05:13
    path feels more natural than the linear
  • 00:05:15
    hack squat so these movements just keep
  • 00:05:17
    getting better and better that said most
  • 00:05:19
    gyms don't have a pendulum squat so not
  • 00:05:21
    everyone will be able to do it I still
  • 00:05:22
    think it belongs in s tier though all
  • 00:05:24
    right last squat type movement for now
  • 00:05:26
    the Smith machine squat seems to be a
  • 00:05:28
    bit more accepted now than it was for or
  • 00:05:29
    5 years ago especially as more top
  • 00:05:31
    bodybuilders gravitate to it I think the
  • 00:05:33
    best thing about the Smith machine is
  • 00:05:34
    that you can actually push your quads
  • 00:05:36
    close to or to failure without that same
  • 00:05:38
    fear of falling over or needing to dump
  • 00:05:40
    the bar and other than potentially redu
  • 00:05:42
    stabilizer involvement it really is the
  • 00:05:44
    same basic movement pattern as the free
  • 00:05:45
    weight barbell Squat and so for
  • 00:05:47
    hypertrophy it also has to go in s tier
  • 00:05:50
    all right let's move on to the 45° leg
  • 00:05:52
    press since you're also flexing and
  • 00:05:54
    extending the knee the quads will of
  • 00:05:55
    course receive high tension however I do
  • 00:05:58
    find that a lot of leg presses don't
  • 00:05:59
    allow me to get as deep as I can get on
  • 00:06:01
    a squat again as far as hypertrophy is
  • 00:06:03
    concerned the deeper you can get the
  • 00:06:05
    better so if you're not able to get your
  • 00:06:07
    calves cheer glutes you might not be
  • 00:06:09
    getting as much out of a leg press as
  • 00:06:10
    you would out of a deep squat outside of
  • 00:06:12
    that though leg presses do generally
  • 00:06:14
    feel good and they are good for overload
  • 00:06:16
    I'm going to put them in a tier now the
  • 00:06:18
    horizontal leg press is worse in my
  • 00:06:20
    opinion because they almost always have
  • 00:06:22
    even more limited range of motion so
  • 00:06:24
    it'll be harder to get high tension in
  • 00:06:26
    the Deep stretch and once your legs get
  • 00:06:28
    decently strong you'll probably max out
  • 00:06:30
    the machine which means overload is
  • 00:06:32
    going to be more limited for
  • 00:06:33
    intermediate to Advanced lifters the
  • 00:06:35
    horizontal leg press is going in C tier
  • 00:06:37
    the lunge is a better glute Builder than
  • 00:06:39
    it is a quad builder in my experience
  • 00:06:41
    even though it will grow both you get
  • 00:06:43
    some stretch and some tension on the
  • 00:06:44
    quads but not as much as you get on the
  • 00:06:46
    glutes they do feel good but if you're
  • 00:06:48
    doing them right you should feel your
  • 00:06:50
    glutes more than your quads you can get
  • 00:06:52
    the quads more involved by taking more
  • 00:06:53
    shallow steps and there's nothing wrong
  • 00:06:55
    with that but I think they're best
  • 00:06:56
    utilized and best thought of as a glute
  • 00:06:58
    Builder as a quad exercise they're going
  • 00:07:00
    in B tier but I'd say they'd probably be
  • 00:07:03
    a or S tier for glute growth all right
  • 00:07:05
    the leg extension this is a surprisingly
  • 00:07:07
    controversial one some people say that
  • 00:07:09
    they're bad for your knees but this has
  • 00:07:10
    been thoroughly debunked now if you have
  • 00:07:12
    bad knees or they give you knee pain you
  • 00:07:14
    should go easy on them but there's no
  • 00:07:16
    convincing evidence that they cause knee
  • 00:07:18
    issues any more than any other quad
  • 00:07:20
    exercise but the great thing about the
  • 00:07:21
    leg extension is that your hips are
  • 00:07:23
    fixed this means that unlike squat based
  • 00:07:26
    exercises your rectus femoris will
  • 00:07:28
    actually stretch and contract here this
  • 00:07:30
    makes it the first exercise where all
  • 00:07:31
    four heads of the quads will be highly
  • 00:07:33
    engaged this is even more the case if
  • 00:07:35
    you set the seat back in fact a brand
  • 00:07:37
    new study found significantly more
  • 00:07:39
    overall quad growth and especially more
  • 00:07:40
    rectus fous growth with the seat back
  • 00:07:43
    leg extension position that's most
  • 00:07:44
    likely because it places the rectus Fus
  • 00:07:46
    under more stretch or it at least trains
  • 00:07:48
    it at a longer muscle length assuming
  • 00:07:50
    you're leaning back and you've got a
  • 00:07:51
    machine that stretches your quads well I
  • 00:07:53
    think they're good enough to get into a
  • 00:07:55
    tier they don't have quite the same
  • 00:07:56
    overload potential as squats do and even
  • 00:07:58
    though some studies do show similar leg
  • 00:08:00
    growth between leg extensions and squats
  • 00:08:02
    those are short-term studies and I'm
  • 00:08:03
    just frankly doubtful that doing leg
  • 00:08:05
    extensions will net you the same quad
  • 00:08:07
    gains as doing squats over the long term
  • 00:08:09
    that said they're still a staple on my
  • 00:08:10
    leg days and they're an exercise I
  • 00:08:12
    definitely think is worth including all
  • 00:08:13
    right the reverse Nordic is the same
  • 00:08:15
    basic movement pattern as a leg
  • 00:08:16
    extension except they have the added
  • 00:08:18
    benefit of being more accessible you
  • 00:08:20
    don't need a leg extension machine to do
  • 00:08:21
    them you can also get a much deeper
  • 00:08:23
    stretch on your quads here the slight
  • 00:08:25
    negative though is that they are really
  • 00:08:26
    tough meaning beginners might struggle
  • 00:08:28
    with them and they can be hard to
  • 00:08:29
    overload with weight so you're a bit
  • 00:08:31
    more limited on your overload options
  • 00:08:33
    you can still add a rep each week though
  • 00:08:34
    or try to get a bit deeper and because
  • 00:08:36
    the stretch is s tier on these and
  • 00:08:38
    they're so accessible I'm going to put
  • 00:08:39
    them in a tier overall but if you find
  • 00:08:42
    them really awkward I'd be cool if you
  • 00:08:43
    drop them back a tier or two all right
  • 00:08:45
    let's knock out three final squat
  • 00:08:46
    variations one that I love one that I
  • 00:08:48
    hate and one that's just okay goblet
  • 00:08:50
    squats are biomechanically very similar
  • 00:08:52
    to a barbell front squat so they will
  • 00:08:54
    highly activate your quads but because
  • 00:08:56
    you have to hold a dumbbell in your
  • 00:08:57
    hands they're actually a lot harder to
  • 00:08:59
    overload once your quads get decently
  • 00:09:01
    strong you'll be able to squat a lot
  • 00:09:03
    more weight than you'll be able to
  • 00:09:04
    comfortably hold so the goblet squat
  • 00:09:06
    will quickly be limited to high rep sets
  • 00:09:08
    only these days I generally only use it
  • 00:09:10
    in two contexts for teaching the squat
  • 00:09:12
    to beginners and as a high rep finisher
  • 00:09:14
    exercise these are just okay for me and
  • 00:09:16
    I'm putting them in C or B tier I guess
  • 00:09:18
    B tier since they definitely can have
  • 00:09:20
    their place jump squats will burn some
  • 00:09:22
    calories and they aren't terrible for
  • 00:09:23
    building explosive power but as a muscle
  • 00:09:25
    builder there are just too many other
  • 00:09:27
    better options out there that'll provide
  • 00:09:29
    more more tension and more overload I'm
  • 00:09:31
    not a fan of these for hypertrophy so
  • 00:09:32
    they're going in F tier Bulgarian split
  • 00:09:35
    squats are brutal but they sure do work
  • 00:09:37
    you'll get a huge stretch on your quads
  • 00:09:39
    and doing each leg unilaterally can be
  • 00:09:41
    very helpful for preventing any left to
  • 00:09:43
    right muscle imbalances but because
  • 00:09:45
    they're so fatiguing and psychologically
  • 00:09:47
    challenging I usually only program two
  • 00:09:49
    sets of these per workout your quads
  • 00:09:50
    will get more sore doing these than on
  • 00:09:52
    almost any other exercise and while
  • 00:09:54
    soreness isn't a onetoone predictor of
  • 00:09:56
    hypertrophy in this case I think it is a
  • 00:09:58
    good indication that hitting the right
  • 00:09:59
    muscle I'm putting Bulgarian split
  • 00:10:01
    squats in s tier deadlifts do activate
  • 00:10:04
    the quads but not nearly as much as
  • 00:10:05
    squats do that's not surprising when you
  • 00:10:07
    look at the side view as far as the
  • 00:10:08
    quads are concerned a deadlift is
  • 00:10:10
    basically a quarter squat you'll get a
  • 00:10:11
    bit more quad involvement if you
  • 00:10:13
    deadlift with a Sumo stance but they
  • 00:10:14
    still don't hold the candle to squats
  • 00:10:16
    for Quad growth they're a much better
  • 00:10:17
    glute Builder and they're an excellent
  • 00:10:19
    overall strength Builder but for
  • 00:10:20
    quadriceps and muscle growth deadlifts
  • 00:10:23
    are going in C tier step-ups are equally
  • 00:10:25
    not fun as Bulgarian split squats but
  • 00:10:27
    also less effective because you get less
  • 00:10:29
    quad stretch and they're less stable
  • 00:10:31
    they do offer a pretty solid glute
  • 00:10:32
    stimulus though especially if you avoid
  • 00:10:34
    lifting off your back foot and they can
  • 00:10:36
    have their place but overall I'm feeling
  • 00:10:38
    C tier on these pistol squats are an
  • 00:10:40
    impressive movement if you can do them
  • 00:10:42
    but the lack of stability and overload
  • 00:10:43
    limitations knock them down quite a bit
  • 00:10:45
    for me if you're limited to at home
  • 00:10:47
    workouts or body weight training I think
  • 00:10:48
    they're great but assuming you have gym
  • 00:10:51
    access there are just so many better
  • 00:10:52
    options I'm going to put pistol squats
  • 00:10:54
    in C tier as a quad Builder squats
  • 00:10:56
    are similar to reverse nordics and that
  • 00:10:58
    they get a huge stretch on your quads
  • 00:11:00
    and don't let the name deceive you these
  • 00:11:02
    are very challenging that said they're a
  • 00:11:04
    bit harder to load so I find them mainly
  • 00:11:05
    limited to adding reps when it comes to
  • 00:11:07
    Progressive overload and I find that
  • 00:11:09
    they have more of a learning curve than
  • 00:11:10
    the other squat options people can also
  • 00:11:12
    find it awkward going up onto their toes
  • 00:11:13
    and getting their knees all the way
  • 00:11:15
    forward but if you can get the technique
  • 00:11:17
    down I do think they're probably the
  • 00:11:18
    best squat option for getting into a
  • 00:11:20
    super deep stretch on the quads so
  • 00:11:23
    despite some limitations I'm feeling A
  • 00:11:25
    or B tier on these I do find them a bit
  • 00:11:27
    awkward though so let's go with B tier
  • 00:11:29
    all right and if I had to Crown just one
  • 00:11:31
    exercise as the best of the best for
  • 00:11:32
    Quad growth I think I'd have to go with
  • 00:11:34
    a hack squat I personally find the
  • 00:11:36
    pendulum squat feels better but because
  • 00:11:38
    most gyms don't have one I'll go with a
  • 00:11:39
    hack squat the one issue with hacks is
  • 00:11:41
    that on some machines you can't get to
  • 00:11:43
    full depth without coming up solid if
  • 00:11:45
    that's the case for you try adding some
  • 00:11:46
    yoga blocks on top of your shoulders and
  • 00:11:48
    then you'll be able to get all the way
  • 00:11:49
    down and if your gym doesn't have a hack
  • 00:11:51
    squat I'd say a high bar barbell back
  • 00:11:53
    squat would be my alternate go-to as a
  • 00:11:55
    number one quad Builder and if I had to
  • 00:11:57
    pick one exercise as the worst of the
  • 00:11:58
    worst I guess it have to be the bosu
  • 00:12:00
    ball squat just get rid of the bosu ball
  • 00:12:02
    and it immediately becomes more stable
  • 00:12:04
    more safe and more effective now do you
  • 00:12:07
    know the best and worst triceps
  • 00:12:08
    exercises if not you got to check out my
  • 00:12:11
