Classic sit ups not bio-mechanicly relevent?

[speedster12]

weighted sit-ups, although used extensively with bodybuilding and lifting sports should not be a part of a sprinters program. Train them generally from many angles, pretty much everything PJ said.

@hemann

Its very excessive training. Should I do 1000 bench press reps or 1000 squats? No.

I know muscle groups need to be worked differently.

Why not do some weighted sit ups, decline sit ups or other various ab exercises? Sit ups are a good exercise, but not the end all be all.

Spend 2 1/2 hours every day doing sit ups?
