I love this workout! It is one of the few upper body only workouts that I own. I have so many great lower body workouts, but very few that focus only on upper (not counting all my splits from P90X or Cathe.)

It has 4 rounds that hit each muscle area (chest, back, shoulders, biceps, triceps.) So, yes, there is some isolation work in here, but many of the moves mostly try to incorporate your core and sometimes lower body also. The chest and back work is all push up and pull-up variations. You can see from the list Dawn provided that the exercises are all have their little "Tony twists" to make them unique.

This is a tough workout. There is very little rest or time between exercises. That makes is very time efficient, but hard! It is more of an endurance workout that P90X. You do moves for a specified time, not a # of reps, and sometimes you could end up doing 30 reps of a move.

I can't see myself ever getting rid of this workout, because it is so unique, plus fun for me. The fact that it is only 40 minutes is another big plus. If you take out the warm-up and cool-down it is close to 30 minutes, making it easy to fit in when time is tight.
