Default Re: doing sit-ups without feet stabilized?

It's because you have a heavy upper body. I have the same problem. When your back comes off the floor there's a moment where you are basically see-sawing on your butt. If you are carrying any appreciable amount of muscle your torso is going to weigh more than your legs and you'll fall back.
