P90X hybrid - Day 45

Back & Bi - man I love this workout.  The Bicep rip is insane.  It doesn't seem to me like any other workout focuses so much on a single muscle group.  One downer was I got a slight left lower back strain during lawnmowers.  I may swap order and do 2 days of Cardio in a row before I do Legs & Back to head into recovery week for Phase 2.  Really hating Yoga now and double up next week.  May do extra Cardio in place one workout.
