Almost finished with week 2 and still can't make it all the way through some of the DVD's. Should I extend phase 1 by another week or two or go ahead and start phase 2? Almost two weeks in and I'm starting to feel great. My arms especially are starting to get bigger and stronger but the beer belly remains. I figure the belly will be the last to go....gotta burn through the rest of the fat first. But I'm still struggling to make it through the second round of many of these workouts....extend phase 1 or move on?
