Do you NEED leg extensions for the textual femoris?

[BeginnerGainz]

*Rectus. Stupid auto correct, but I figured y’all would of got what I meant.

Or are a combination of full active ROM unilateral and bilateral movements for hypertrophy?

[Camarija]

Maybe it depends on your own leg anatomy?

I'm tall and have these long legs, and I can't really hit my rectus femoris without either leg extensions or sissy squats.

[TheShadowMan]

I like them cause you also have the option of lowering the weight, and doing one leg at a time, and getting truly brutal isolation for the quad - but it does make the set take a bit longer to work both legs that way. I like when exercises allow for less weight required to produce a good stimulus though. I work out at home so I mean I don't have a commercial gym's amount of resources, so if I can use less to burn more, i'm all for that.

I guess some may not need them just like some people don’t need ab work or bicep isolations, but I definitely think they help for full development.

[SuffolkPunch]

It is a bi-articulate muscle (spans both knee and hip joints) which means it is not trained well by movements which have both knee and hip extension at the same time.

It gets used for example when kicking a football (which is hip flexion and knee extension).

So you need to anchor one joint or the other join. Leg extension and sissy squat keep hip fixed. Maybe situps train it..? I haven't tried keeping the knee fixed.

Perhaps you could do some kind of kicking movement with a cable or band for resistance attached to your ankle.

There is this device called MonkeyFeet that can be attached to your foot and you can put a dumbell in it.
Or, the cheaper variant attach the dumbell with a strong enough elastic.

Single leg lunge with bench and dumb bells

Pistol squats

Sissy squats

In physical therapy after my knee surges, Id sit on a bench and use a weighted cable machine to extend my knee back and forth

Cycling with resistance

[Garage Rat]

As mentioned the sissy squat weighted or unweighted can help.
Make sure you use a full range and do them correctly.
Start with unweighted sissys and get those down.
You should be like your almost kneeling with knees going towards the floor.

[BenMcLeodNZ]

Yes, you pretty much need them if you want to work the quads to their max

[GeneralSerpant]

Rectus? Straight messed us up.

I was surprised to find out that there's a lot going on past the hip end of the quads when doing leg extensions in order to get full strength.

[coachcalande]

There have been studies that would say yes

This is the conclusion I’ve come to as well

[MyEgoProblem]

Aye..
As sp said.
Its a case of simple biomechanics.
Squat patterns ain't the winner here.

Simplest way! You need either knee extension without hip involved Or hip flexion without knee involvement.

Basically gives you leg extensions, proper sissy squats or leg raises to a degree and any splash over you get from just quad work in general.

If you can do fully flat (hips in extension) sissy squats in the bench. That would be the quad equivalent of a nordic. As s would make you a legit freak!

[GeneralSerpant]

-Sled pulling with rigid knees.

[BenMcLeodNZ]

It's interesting though, if there aren't real life conditions where there is significant load on the quads while they're fully flexed (aka no exercise does it), then functionally nobody will miss it. It's just a bodybuilding thang.

Kicking a ball too.

I seen soccer players do standing leg extensions with a cable machine and a cuff.

I mainly considered getting this during gym closure, but I still think it's pretty handy for various hamstrings isolations and bilateral hip raises.

Yeah see.
