Do Yoga. This is one of the best ways to stretch it all up, and cool your body down. Also, yoga is a great way to stress it all out, and relax by stretching every single muscle in your body. You can do yoga in your rest days.
#Sun Salutation (Suryanamskar) is the best exercise!!! Perfect as warm up, stretching and repeated several time as conditioning for the entire body! #yoga try it! Good for me if I modify a few poses to accommodate my bad arm.
