I'm back after vacation. I intended to workout on vacation and even got in one workout, but when it hit 94 outside doing the Shred in an unairconditioned house inside . . . . well, it didn't happen. We've been back a week now, and I just finished my second Shred 1 of the week. My continued improvement is encouraging. There is still plenty to challenge me on Level 1. Any suggestions for a DVD with which to alternate Shred 1, keeping in mind that bouncy things like running and exercises requiring coordination are out?
