Poof Legs From extensions Only

[Vespa103]

Ok I know everyone is going to flame and say you hae to squat leg press etc etc

Thats not true I believe I have seen the best argument that leg extensions alone can build quads

Here it goes I am in the gym and I notice a woman on the leg extension machine

I noticed that she had great quads I am talking seperation + mass

I also noticed she had the same scar I have down the midddle from an acl surgery

Now this girl did not train anything else I mean no other weight training at all she did not use any AS and the only develepment she had anywhere were her quads

I asked her what she did and she said the only thing she did was leg extensions this girl did not do any other training. She did the extensions to rehab her leg from surgery

So what do you guys think growth from leg extensions alone possible

Do we make routines to complex can one exercise an isolation at that promote growth

PROOF not POOF

Correction

I HAVE A GOOD IDEA

DO LEG EXTENSIONS ONLY FOR 1 YEAR AND LET US KNOW. ARE YOU WILLING TO DO THAT SO WE CAN FIND OUT?

 

[Extreme]

LOL

That is one of the funniest titles to a thread I have ever saw. And from my near 3 decades of lifting could very well be true!

correlation does not equal causation man...it is very possible the female in question has great genetics for leg development..

Agreed... the best calves I've ever seen on a woman off the stage was on a 55 year old woman, doesn't work out.............. she's a golfer.

SS


I said golfer....not gopher.

Yes I have seen incredible calfs on people that do no training and I agree calfs are definately genetic

However quads are not calfs while size may be genetic muscle develpment is not this was distinct quad seperation from weight training not genetics

This girl had no other muscle anywhere on her body

You guys can continue do train however you would like

but for people with real joint issues (lacking menescas, torn ligaments, hardware etc etc)

I do not think it is necessary to squat you can get develpment other ways

Obviously squats do other things than quad develpment and are great for overall power but I am talking for the quads only here

For older guys that already have thickness and are starting to get a little beat up consider dropping the squat

NOW I DO AGREE WITH THAT.

Leg extensions are worse for your knees than squats.

Welcome dr. livingstone!

Leg extensions are worse for your knees than squats.

My thoughts are that "heavy" leg extensions are MUCH harder on the knees than "proper form squats." Now as bb'ers, we cant just do an exercise without continually increasing the amount of weight used - that's what causes injury via leg extensions IMHO.

 

[bigbaldbulldog]

I need another 4-6 iches on legs and drop my bodfat about 5-7% and to top it all off i need calves..

Any ideas?

Bad knees, bad lower back and bad hips...

I have heart and desire ......

Why are leg extensions hard on the knee joint?

To understand why this is, it is helpful to understand the concept of shear. Shear in this case just refers to a horizontal force on the joint. Imagine two cans stacked on top of one another, and imagine that a piece of masking tape joins them. Then, imagine what happens if you hold the top can still while you push the bottom can to one side. Eventually that tape will snap. This is a simplistic description of what happens to the knee joint in a leg extension.

Here is a simple diagram that attempts to explain the difference between the squat and the leg extension. The black lines represent the thigh bone, shin bones, and knee joint (black circle). In a squat, as shown in the figure on the left, your feet are on the ground (hopefully), and the force of the load is transmitted downwards, along the length of the bones. In a leg extension machine, there is a pad against the front of your shin or ankle, and you press against it to move the weight. The foot swings upward in an arc. Thus, as you can see in the figure on the right, the pressure is coming across the shin bones, not along their length. This creates the problem in the knee joint as the shin is pressed backwards.
Leg extensions do have their place, usually in rehab. If the leg extension machine is used, it is wise to use a smaller range of motion, perhaps the top third of the movement (from slightly bent to fully straight leg), and light weight.

I like the idea of doin the top third..gonan try it and see...only after i do squats or as a prefatigue to squats...

What types of mobility problems?

I’m as flexible as your average geriatric, but I still am able to leg press and hack squat

some blockage on the front of my ankle from a wrestling problem makes it where my knee cant go too far in front of my foot

I see

You can’t leg press and hack squat?

Like.. setting up your stance with feet higher on the platform so that your knees don’t go over toes?

I always thought leg extensions were bullshit. At best an adjunct to something that truly drives hypertrophy. I might have tried doing them twice in my life and immediately dropped them after maybe a few weeks.

My quads were at their biggest ever years ago when I was natural and only doing leg presses. No squats, no hacks no lunges, no deads, no other quad weight lifting of any kind.
