This is a 35-minute video that is part of the Billy's Bootcamp series that comes with the Billy Bands. But this workout does NOT use the bands. It also does not include any traditional kickboxing moves, i.e. punches and kicks. The first half of the workout is standing abs including quick torso twists, standing forward and side crunches, and knee raises. The standing work does not have a cardio effect. It is standing ab work. The second half of the workout is on the floor and includes some really tough crunch and sit-up variations. It is structured similarly to Michael Olijade's Killer Abs & Back, but Ab Bootcamp moves at a slightly slower speed.
I really enjoy this workout. I see myself using it regularly.
Billy, like always, is very motivational, although not everyone likes his style.
