Bro's had a horrible week as a chelsea fan😂 can understand the frustration

Hi Martin. I think this video raises completely valid points about both of these exercises having very little functional carryover. However, I think you also are taking them out of context. From my 2 years of lifting experience for both myself and people I see at the gym, people typically do these machine exercises at the end of their workouts to satisfy that demand for a little bit of extra volume.

I totally agree that compound/functional movements should be the priority, but that's obviously for the beginning of a lifting session when the muscles are the least exhausted and can create maximal force production.

This is why Nick Smith does leg extensions/leg curls while standing up to prepare himself for real world activities

"When in real life are you floating in the air extending your legs"

Brave thing to say while wearing a football jersey.

As for leg curls, knee flexion strength is one of the biggest protective factors for avoiding hamstring injury while sprinting. Particularly eccentric knee flexion which in sprinting occurs OKC.

Open chain means when you don't have a constraint on the final movement and close chain means when you have a constraint on the final movement.
So pull ups, Squats, bench press are open chain exercises and lat pull downs, leg press, leg extenision, smith machine bench press are close chain exercises.

[LilWillieBeatz]

most people dont use leg extension as a replacement for the squat they just impliment it into their workout. Your idea of how many people only use leg extension over squat is scewed by social media. for someone thats breaking out of the fitness matrix u sure seem to be stuck in it

[Liatofek]

They're like a chest fly an isolation movement you do them as a supplement movement not a main movement if you are using them as a main movement that's when there's a problem

[אורןקלר]

Are your opinions about isolating the triceps and biceps the same? because they are the quads and the hamstrings of the arms

[BobTheBever]

Do to a knee injury. My fiscal therapist said I can never do leg extensions ever again. Perfect I just do some squats

[RZboy-HYBRID.WORKOUT]

Definitely agree with his take here especially when it's supposed to be a supplementary exercise and not replacement.

[quantom]

Bro wants core activation in evey exercise. Leg extensions are an isolation not a compound movement. Bro is a master at yapping no hate

[G.Bfit.]

Man being against Leg Extensions and Hamstring Curls is like being against Bicep Curls and Tricep Extensions or Pressdowns. There is more to bodybuilding than "being functional/athletic" dude. Is that important? Yes! Is that the end all be all? No! I say this as someone who supersets leg extensions with sissy squats and supersets leg curls with nordic curls.

[bznshee]

I mean in freestyle wrestling leg curls and hamstring curls are functional for that sport. There may be better movements for leg curls but hamstring curls replicate the strength of defending a leg lace pretty well. You’re right overall though

[Perstion-mmld]

This guy knows what he’s talking about . Really good teacher at this, explains this stuff really well and has character.

[JakeCluff-eo]

This is some really terrible advice. This is good advice if you go to the gym with the intentions to hit only the leg extension…that’s kinda why different workouts are included in a workout! To hit of your legs and core. Leg extensions are great for quads, include other excercises to further enhance your legs and agility

[CruzBoxing]

I see you always make video on MMA, but is it possible you could do one on boxing? Would like to know what type of squat variation and depth would be optimal for boxers and everything else. Thanks!

[himanshunagar]

Bro at this point I cant tell who's who
These brothers look EXACTLY the same

[ghostlycraft]

This is why Leon Edwards has the most aesthetic body in the entire universe!! 🌌

[vChava]

This is why Liam Edmund has the best leg extensions

[rxgpudp]

Sup martin, my kickboxing coaches have me do situps and rotational work, but will these make my waist blocky?
