Classic sit ups not bio-mechanicly relevent?

I remember throwing a basketball in to a wall many times, daily, for several weeks. I desperately wanted a med ball, but it would have made too much noise and would have damaged the indoor wall. Dam it, I’ll go and purchase a decent medicine ball, if med ball throws in to a wall is good training. Even after the basketball throws, I noticed a differance in my running.

You was faster at sprinting after 2-4 weeks of this training method? Or you just ‘felt’ faster?

I can see how med ball throws in to a wall, would be far more relevent to running , than just doing crunches and sit ups.

With the med ball throws in to a wall, atleast you are in a standing position.

Med ball throws in to a wall are much better than sit ups & crunches in my opinion.
