Classic sit ups not bio-mechanicly relevent?

[speedster12]

we are not talking strictly about sit-ups.

I don’t think there are many, if any, on this board that can do situps at 1/sec for anything over 100 situps. And I can’t see any valid reason to do 30 sets of 100 situps even if its spread out over the day. Its not close to being specific to sprinting and there are better ways to develop fitness that take a lot less time.
