I'm halfway through Phase 3, and was a little worried in Phase 1 because I thought it might be a bit too simple. Phases 2 and 3 changed my mind. The workouts ARE different between phases, and the reps and execution of the workouts are different within phases (e.g., sometimes you do 2 sets of 15, sometimes 3 sets of 10, sometimes you change the order, etc.). You truly do not do the same workout twice, and interestingly, it really does make a difference. The nutrition is key. It will require attention and diligence, and you can't expect to exercise your way out of bad nutrition choices, but they can't make the program any clearer.
The user is not off the hook; it requires discipline and perseverance and consistency to change your body. But if you bring those three traits to THIS program, then change you shall. The best thing is that, once the 80 days are over, you can do it again, and it will still be a challenge, because there's always a way to do the workouts better, lift heavier weights, tighten nutrition, etc. The results will keep coming. It is NOT A QUICK FIX. It's WORK. And IT WORKS.
Bottom Line: Yes, I would recommend this to a friend
