This is a great workout for getting into shape or staying in shape. These exercises help build flexibility and strength. The exercises start out simple and slowly build in complexity. If you get to a point where you don't feel quite up to moving on just keep doing the exercises you are comfortable with until you feel ready for more. Most of the exercises are simple enough that you can do them anywhere. You might get strange looks from people, but don't let that stop you.Amituofo! Train harder!
