Each week in the PH3 Trainer utilizes the same split, so you'll become more comfortable with the routine as time goes on. What will change each phase, however, are your deadlift, squat, and bench-press maxes.
Each week, you'll be challenged a little differently. Some days you'll use heavier weight, some days will include more reps. Whatever happens, be sure to do the workout exactly as I've programmed. I know you'll feel great about the results.
