This is exactly kzbin.infoUgkxUHHotQRjIQnfuxEeVotlkHVYWH0DXZoS what I needed to get some exercise while I'm stuck at my desk all day. It's just the right size. Only downsides are that the right oeddale unscrews itself while I use it and increasing the tension causes it to squeak while in use. Both are minor issues that aren't that important to me. So I give it 5 stars.

[@nic0fpvnicolas606]

Hey dr mike. I know I'm 3 years late but I think you are wrong about the physics a 5:30. The moment arm is higher when the pad is on your toes, so the force you feel against the pad is lower. However the internal force on the quads is the same. The easiest way to see it is to look at the weights. If they are moving the same distance the amount of work produced is the same. And the amount of degrees of rom is the same. So the quads must produce the same amount of force regardless of the pad position.

[@femoris8502]

[@DCJayhawk57]

If you don't have access to a leg extension, try subbing in banded sissy squats. The band behind the knee resists terminal knee extension, meaning you have to forcefully contract your quads to lock out. To me, it feels like the terminal knee extension on a leg extension but without the sheer force on the patella. I load with a kettlebell or dumbell for straight sets, but doing bodyweight myoreps is maybe the best use. They're totally doable for home workouts and I don't think you'll find a better quad iso exercise for home (with so little equipment).

[@amandacasimir7320]

Im envious about these guys calves, over the last ten yrs my calves have both had some sort of congenital defect rear its ugly head and both my gastrocs inner heads have disappeared entirely and one even ripped off when just warming up. no doctors or even a specialist can tell me what this is or if its gonna get worse and destroy my entire gastroc eventually? any ideas?

[@kravmaga7070]

I currrently do 5 to 10 reps on leg ext for slow controlled contraction, 1 sec peak hold, slow eccentric for as bloody heavy as i can go to failure and burn and rest pause a couple reps then stumble over to squat rack and do either 10 rep squat with as mcuh weight as possible or half as much weiight and do step back lunges to failure. I do this to really target my quads w/o loading too much weight on my lumbar disks as my 50 yr old body cant handle 2 x body weight squats anymore.

[@classof13tre]

it sounded like "quality of wife" to me

[@samuelprietolima1330]

In mistake #4 doc mike makes a mistake in saying that the reason putting the foot attachment too low makes it harder is because of moment arm. It's only harder because of instability/pain. The increased moment arm between your quad and the pad is by definition compensated by decreases moment between the pad and the actual weight. The muscle contraction/weight movement ratio is constant

[@funygameur]

Legs Extension: - Low Weight - 15-30 Reps - bend of knee right in the corner of the seat of the machine - feet blocked in the ankle or higher but no. - controled centric - max range of motion - toes pointing: wheres it comfortable for you, if you're not an Olympian we don't guve a fuck.

VERY GOOD CONTENT SUBSCRIBED

[@nicaguitar]

Thank you for the great videos! I had a question. Ive had historically alot of problems with my left knee (quad and patellar tendinitis) which has been fixed for a while, but I ditched the leg extension a while ago because Ive heard/read alot that it wrecks your knees. (tbh, I used to put too much load before to do 8-10 reps and that probably has to do something with it). Would you recommend doing the exercise with this background? Again , great videos as always! big fan!

[@Adrian-cn5rk]

It's up to you whether you want to implement the exercise. No one movement is needed, with that being said play around with different positions, lighten the weight, squeeze the quads from the start of the movement and not only at the top or just lockout about 95% of the way. If the problem persists, ditch it.

[@nicaguitar]

@@Adrian-cn5rk Thank you very much for the advice! ill try it out next leg day .

[@tomlongam7653]

For me this is a huge question....I mean for over a year I did it it was ok...but yesterday I did it and one day afterwards I have pain on top of knee...first time I had this type of pain ...like just above. It is weird. I wonder why. What went wrong? Is it because I pushed the pad to far? Or positioned the seat badly? I mean the weight was certainly not huge....

[@imcfr5897]

Thanks mayn ✊♥️

[@Siberius-]

Why are there no lying leg extension machines? that would put a stretch on the quads and be like a reverse Nordic Curl, but the machine hardly exists for some reason. There's a seated and lying version of the leg CURL, but not the leg extension (there's some very rare exceptions out there). Edit: Wait I figured it out. It's because both a sitting and lying leg extension machine, don't put much stretch on the quads either way. The Reverse Nordic Curl ROM is required to actually get a full stretch, which is a lot more ROM.

[@lecobra418]

On the leg extension attachment on a cheap bench you can do that.

[@Siberius-]

[@jonnyboz]

How do I find the series playlist for these!?

[@Adrian-cn5rk]

I'm inclined to disagree with the first tip. My knees hurt on the lockout..even with light weight, and good form. N it works just fine going to near lockout for me.

[@Lotusdreams]

That is why he keeps telling you to chose the form that is as close to the optimal as possible WITHOUT causing pain or joint discomfort. As long as you keep it consistent and try it out there is no way Mike would disagree with you. Doesn't make sense from his optimal muscle growth perspective since pain will stop you from maximising output and neither from mine, as a PT, since the full lockout can indeed stress ligaments and over time cause injury. But that is why you need to keep applying his tipps to your needs and Mike still should recommend a ROM as high as you can handle since not everyone will have that problem

I've tried leg extension + either bw squat with extra heels or sissy squat Best pump I've ever experienced in my life, not even high reps just 8-10. Question: Will this carry over to a squat?

[@JAREDFEATHERRP]

If you grow muscle in a massing phase in your quads and then go back to squatting in anothet massing block then yes. Your squat will go up over time as you build muscle.

[@hoyasfan459]

There was a guy at my gym who practically stood up in the machine when he lowered the weight and used his body weight to get the weight up on his next rep.

[@jamesbrincefield9879]

Anyone have any tips for a leg extension/leg curl attachment for a bench? I always notice the seat on the actual leg extension machine is leaned back for a better ROM and my bench isn’t able to do that. I’ve never seen any videos covering form tips for using the leg attachment.

[@EsmaragdoGonzalez]

Am I supposed to lift the pad with my feet or lift the pad by extending my quads?

[@mizakzee]

Jared's calves are the size of lesser men's shoulders.

[@dodgingrain3695]

I call BS on you can produce a large amount of force. Of course you can but it takes a lot of time to get there. I haven't met a leg extension that has a decent design I can't max out for 3 sets of 6-10 reps with strict form. Also its a great machine for doing single leg reps. and working on strength imbalances. Toes need to be pointed towards the sky as much as possible to hit heavier weights. If your doing leg extension right you should have trouble standing after the set.

[@soemtheng9704]

For those with hyperextented knees, should you go Full ROM at the top aswell ?

[@ecosan8914]

I bursted ounof laughter with the last mistake XDDDDDDDDD

[@Kickbackske]

Just got into a disagreement with a guy at the gym about leg extension hoping someone can clarify. I always have the machine positioned on the last pin so the angle of my legs goes slightly passed 90 degrees when I come down on the negative to achieve imo full range of motion. This guy at the gym is saying there is NO quad activation when you go passed 90 degrees and it is only damaging to your knees. Hoping someone can shed some light. Thanks in advance
