Workout Update: P90X Day 31

Day 31 was the first back and biceps workout in Phase 2 of P90X. It is the second "new" workout after the first month. Like the Chest, Shoulders, and Triceps workout, this one incorporates many of the exercises from Phase 1's Chest and Back and Shoulders and Arms workouts. And, it adds a couple of new exercises into the mix. It has two blocks of work with a one-minute rest between them. You alternate two back exercises (one that is a version of a pull-up and one that uses weights) followed by two biceps exercises. The workout ends with a strip set of bicep curls, where you do 8 reps with the heaviest weight you can use, then drop the weight (5 lbs or more), do eight reps with the lighter weight, and repeat that two more times. So, it is a challenging workout and it does get tiring toward the end, especially once you get to the point where you can do more pull-ups at the beginning.
