Yes if you have good quad genetics
But they won't be as big as they could be because leg extensions bias the teardrop portion of the quad and don't hit the rest of the quad crazy hard. You essentially have to do some sort of quad pressing movement as well to maximize your quads
amount of volume is completely irrelevant. you will frick your knees up if you perform the exercise with bad technique and/or ego lift, as with any other movement
Will doing it controlled and high reps low weight strengthen my knees?
Personal experience. just try it morons. It doesn't matter if you do it all controlled and nice, it will eventually frick you up.

>rectus femoris built shortened makes sure u will never stand straight, that ur pelvis forever stays tucked like an beaten dog hides tail
nothing personel kid
sure, just like jamming humerus into acromion in slow and controlled manner will fix ur shoulders

Is this sarcasm? I’ve been doing more or less that and it’s helped my shoulder
>Is this sarcasm? I’ve been doing more or less that and it’s helped my shoulder
yes it is sarcasm bot, and no u didn't fix shit by going sloooow in moronic manner, don't act daft bot
to fix shoulder one needs to extend thoracic spine and restore mobility to scapulae, obviously
same for quad development

so on top of it being basically cloombing drop knee (exactly like BSS) type of movement u're fricking up ur posture, and with fricked posture there is joint problems because it will show up somewhere else like sacral-iliac joint for ex (that doesn't take into account that u will look like shit with tucked pelvis)
Done leg extension as a main exercise for 6 months while my hip flexors recovered and developed "knee cap" pain. Took 1 month off from that machine while re training the squat and the pain went away.
knee extensions are a little rough with patellar tendonitis, although they are recommended for later stages of rehab. So they aren't good for acute knee injury, but they are pretty good for maintaining knee health.
Usually tendonitis problems are load based, so if you slow down the movement, the pain subsides. People tend to not think of load as a unit of velocity as well.
i do these with a band and laying back at about 45 degrees to hit my rectus femoris specifically, since it doesn't get much training from normal work. If you can't do an L sit, its likely because your rectus femoris starts cramping
No, because quadriceps muscles perform two major function - knee extension and flexion at the hip joint. If you do knee extensions alone, rectus femoris(the middle part) will end up doing less work and will not grow as much as it could be
>If you do knee extensions alone, rectus femoris(the middle part) will end up doing less work
wrong. If you shorten the fibers of the rectus femoris, you will turn it off, but if you lean back and lengthen it, the rectus femoris will actually become a dominant muscle in the leg extension. I use leg extensions as my primary rectus femoris exercise, reverse nordics will also work it.
Learning anatomy and biomechanics will serve you very well in lifting
>but if you lean back and lengthen it, the rectus femoris will actually become a dominant muscle in the leg extension.
no it will work against itself bottot - good analogy is flexing bicep by bending elbow all the way up, releasing some and flexing again - u can easily frick it up this way, joe esthetics (rest in piss) torn bicep this way

also shite movement unless u do exactly the opposite of what u r taught - want more of my musings on squat?
should I start doing these? I almost never do. I've mostly just been squatting and front squatting lately.
if u wanna frick up u r knee and more - go ahead
there's a reason this exercise hurts - it is shit, and that principle extends to all of movement - if it hurts u r fricking sth up be it through not the movement intended really (that u don't realize), or the movement is not good at all for some reason, the latter is the case here with quad extensions

You know there are other muscles in your legs apart from quads, yeah?
that's why I specified quads you buffoon
He literally said
>build big quads
Is this board just bots and morons?
Yes.

False. You can't isolate the teardrop portion of the quad.
>bias
you can't
Because the sheer volume needed for it to happen, you will frick up your knees before doing so.
>source: my ass

yeah, you personal experience with garbage form and egolifting
we are talking about normal guys who don't do stupid shit here

wtf are you on about you moron? How long are you talking? I've been doing leg extensions for 2 years and have had zero knee problems
Done leg extension as a main exercise for 6 months while my hip flexors recovered and developed "knee cap" pain. Took 1 month off from that machine while re training the squat and the pain went away.
bullshit. i do the quad machine with the full stack and have never had any knee problems.
if you want knee problems do squats
knee extensions are a little rough with patellar tendonitis, although they are recommended for later stages of rehab. So they aren't good for acute knee injury, but they are pretty good for maintaining knee health.
Usually tendonitis problems are load based, so if you slow down the movement, the pain subsides. People tend to not think of load as a unit of velocity as well.
I stopped doing these awhile ago. I only do squats and seated leg presses for quads now. I should re add leg extensions
i do these with a band and laying back at about 45 degrees to hit my rectus femoris specifically, since it doesn't get much training from normal work. If you can't do an L sit, its likely because your rectus femoris starts cramping
Instead of all these memes why don't you just squat? I only squat and have bigger legs than any of you.
>encouraging the machinegays to leave their machines
let them be weak in peace
No, because quadriceps muscles perform two major function - knee extension and flexion at the hip joint. If you do knee extensions alone, rectus femoris(the middle part) will end up doing less work and will not grow as much as it could be

Sure if you have a machine where you can lean back but that’s not common

also me:
I could imagine doing leg extensions alone is bad because your stabilizing muscles become underdeveloped. Squats are good for you, Anon. Do both.
Do squats you weak homosexual
also shite movement unless u do exactly the opposite of what u r taught - want more of my musings on squat?
