The first rule of working out is to enjoy yourselves! Much of what you do and what you don't do will depend on whether or not you are having fun. Beyond that there are plenty of different exercises and activities you can do that will encourage recovery and improved health. I have created two lists that may be helpful.
Growth and Recovery: You are in your growth period trying to gain muscle and actively improve health.
-Jogging, speed walking, elliptical, etc...
-Sports and competition.
Recovery: You are sore and need time to recover. Some light activities will help you do this.
-Tai Chi and moving medication
