The world’s best home six-pack circuit

The first mistake guys make when trying to build a six-pack: targeting their abs. If you really want to sculpt a washboard core then you’ve got to be smarter; sit-ups alone won’t cut it. You’ve got to train your entire body to rev your metabolism. And you’ve got to add a whole lot of sweat to your workout.

Thinking you need a gym to muscle up your midriff. Exhibit A: this lounge-bound total-body workout from expert PT Adam Stansbury that relies only on your bodyweight to get you that little bit closer to single-digit body fat.
