Classic sit ups not bio-mechanicly relevent?

So what’s the point of using momentum??? What is this corssfit???

In high school, my younger bother did 1234 sit-ups and still holds the school record. He needed a pass from the PE teacher because it went into the next class session. 1234 sit-ups = more than 1 hour. My calculations are not way off.

Anyone have the guts to prove me wrong??? Didn’t think so.

I once did 1000 sit ups in a row. It took me about 30 minutes.
