Dancing to tone up

I'm doing some dancing to tone up my body. It's something I've done from time to time. Mom also uses dancing to gage how well I am energy wise. When I was injured I could only do it a short while before getting out of energy. That's bad but luckily as I've gotten better and in less pain I've gotten back into dancing and I am able to go longer and stronger. It also helps I am on medication that helps with a side effect of back issues.
