a ton of people say leg extensions and curls are shit exercises because they don't train you for functionality, among other reasons. However, when you tread water aren't you just doing LOADS AND LOADS of leg extensions and curls?!?!? It seems like these exercises would have some functional cross over for swimming, deep sea diving, and water polo. what do you guys think?
AND yes I do know that there are better exercises for legs, but the point of my post deals with the functional cross over for leg extensions/curls, not which exercises are the absolute best for developing legs
