I decided to change up my workout routine a little bit today.  In addition to the push-ups, pull-ups, sit-ups, etc. (which can get monotonous, but they have to be done) I decided to attend a yoga class at the Y.  I get in enough strength training, which targets power and durability, and running and elliptical work, which targets endurance, but, as I get older, I feel the need to focus more on flexibility, joint health and recovery.  That's where the yoga comes in.  I'll be attending these classes at least until the end of the cycle.
