leg extension might be good for bodybuilding, esp for bringing up the VM… but functionally they’re pretty useless (if you participate in sport) - Mainly because they train a motor pattern that you’d never use and they put a shear force across the knee which isn’t very healthy…just my 2 cents.[/quote]
I think that’s pretty misleading. If you make your quadriceps stronger - you will be able to run faster. My best friend has an elite 100m and he can do leg extensions all day with 250lbs.
Those whole bodybuilding vs. functional arguments are bullshit.[/quote]
Agreed. It holds no water and personal trainers get clients by spreading this bullshit.
The belief that a stronger bigger muscle can somehow ONLY perform the way it was trained makes no logical sense.
It implies that squatting or leg extensions won’t help you push a truck down the street. Using this logic, you could only push a truck if you trained doing walking lunges.[/quote]
I replied, not sure if it didnt post or was deleted? - I have no idea how you came to the conclusion i was implying bigger muscles wont perform in different ranges of motion…All i was “implying” was that for athlete’s there a LOT better exercises (both from a strength, functionality and prehab angle) - and what i said holds plenty of water mate, read ANYTHING and you’ll find that out.
And if you dont think there is an argument for functionality, you’re just a plane out retard.

Functionality is a very context specific thing though, isn’t it?
Perhaps leg extensions wouldn’t be very “functional” for things like running (although even then it’s debatable), but for things like kicking a soccer ball, punting a football, or “round/thai kicks” in martial arts they do a hell of a lot better job of mimicking the specific movement pattern at the knee joint than things like squats or lunges.
People have to be careful throwing around the term “functional” without also stating the specific context that they are using the term in, or using it as some generalized term.
