You'll notice that each week of Phase 1 gets progressively more difficult. The workouts are the same, but you'll be doing some additional reps. Bear in mind you're not doing a ton of additional reps each week, but those reps that you do add will make a big difference in your results, especially if you use even more weight than you did last week.
That progression is what makes the True Muscle Trainer so effective. But, taking those steps toward your goal comes only from hard work. I can only tell you what to do, you're the one who has to do it.
If you don't remember how to do the warm-up exercises, or need some coaching pointers, make sure you go back to the video on Day 1!
