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]
Don’t tell me what i was implying, because you’re an idiot - I said for a sporting person(ie footballer) training your quads with isolate training is stupid, not only because it has limited functional cross over(ie waste of your time), but it doesnt protect any of your joints in movements such as running and cutting. I didnt say they were useless, just that there are better ways to do it. open your minds and stop jumping on people who have a different, and probably more informed opinion than your own.

You don’t have a more informed opinion. You are in a bodybuilding forum giving advice out of context to football players who didn’t ask for it. If that makes sense to you, how am I the idiot?
Isolation work is not useless to an athlete. An athlete would obviously not devote all of their time to it, but the belief that a leg extension is somehow “unfunctional” is nonsense. Any exercise that can make a muscle stronger can not be useless in a strength sport.
None of that matters, however, since the op did not state he is a football player and didn’t ask for that advice.
