Last week Dianne and I tried out Level 1 of this Jillian Michaels 6 Week Six-Pack abs routine. The DVD includes two 30-minute workouts plus warm -ups and cool downs. You are supposed to start with Level 1 for three weeks and then advance to Level 2 when you are ready. Jillian's approach does not include a bunch of boring sit-ups. She leads you through two sets of a cardio circuit that tones your abs.
I thought this was a very good way to mix up your core exercise routine. It was challenging, and I definitely "felt" it the next day. I also liked that it wasn't just my stomach that was achy. I was sore in my obliques and my back as well. The second time we did it, I didn't notice that I was sore at all the next day. I think I could have moved on to Level 2 right away.
If you are looking for a good ab routine, you might consider this DVD as an alternative for your endless crunches!! Do you have a favorite workout video that the rest of us may be interested in?
