Query: Fun and Tough All-Around Workout, Not Just Abs

6 Week 6 Pack is a great workout - I had fun doing both level 1 and 2, found them both very challenging (especially level 2) and I switch up between level 1 and 2 with other workouts. I often tack on 6 Week 6 Pack to a Ripped in 30 workout and find that I get a great 45-50 minute workout that leaves me feeling energized and accomplished. Something that I like about both level 1 and 2 is that they seem to go by really fast and I never get bored. Unlike the Shred workouts and other JM DVDs, the longer circuit keeps things interesting and doesn't feel repetitive. The only downside to this setup is that sometimes I'm dreading one move knowing that it's coming towards the end and I can't get it over with 'til then.I also felt that these 2 particular workouts added a new definition to my body (not just in my abs) that I hadn't had before. I use 4 lb. weights, and find that it provides me the right amount of resistance to the moves.Thanks, Jillian!
