Jumping jacks

100 jumping jacks? Why in the name of sanity would anyone do that, and what's the point (apart from knowing you can do it)?

This reminds me of the sad fact that some martial arts styles and schools still use outdated and sometimes pointless or outright questionable exercises.

Story:
Sally Burke has a hard time sitting still. She finds martial arts to be a good outlet for her energy and can't imagine life without it.

"That would be like taking that thing you love most and say you can never do it again," Burke said.

That worst case scenario almost happened seven years ago. After completing 100 jumping jacks, pain overwhelmed Sally to the point where she couldn't walk.

"I didn't do them any differently then I did any other time," Burke said. "I guess it just hit the nerve that time."

Doctors diagnosed her with Spinal Stenosis. She tried cortisone shots and radio frequency treatments, but they didn't work in the long run.
