I’ve read about this particular exercise being used FOR knee rehab so this just throws me off a little bit here.
Leg extensions put a lot of shearing force on the knee that is unnecessary and the benefit to risk ratio is not in it’s favor.
Cressey talks about it, among many other well respected people.
They are used in rehab with the amount of weight is so low that any shearing force will be negligible and the idea is just to get the quads firing.
Leg extensions have also been shown to cause the quads to fire at different rates than what is natural.
I think if you look at a lot of athletes and knee injuries that shouldn’t have occured (Tiger Woods for example, how does a golfer tear an ACL, lol), you will find that leg extensions are part of the routine.
While for a BBer they may not be the devil in causing knee injuries like in sports, they still cause wear and tear on the knee that doesn’t need to be there.
That’s my .02
I know Prof X says he had a well respected ortho (IIRC) say if done properly they’re fine for the knee, I just still don’t see the need for them when there are many other great exercises for the quads[/quote]
I was thinking of using this to help get my right knee up to speed for squats again so I was thinking of going high rep anyway seeing as its always free for use at my workout time.
Very informative post, thanks alot!
