Earlier this week, when my son was flipping over the couch and doing roll-overs with ease, I said Joseph Pilates would be pleased with his strength and flexibility. My son was surprised to hear that Pilates was actually the given name of the inventor. I was shocked by Trey's oblivion--10 years of my preaching and he did not know Pilates 101 history? This animated explanation provides a great background on the system Pilates termed Contrology--it is our mind that strengthens the body. Enjoy!
