Bodyweight Training: Crab Walk towards a Shredded Six-Pack

What It Is

A 15-minute four-exercise total-body circuit from L.A.-based celebrity trainer Andy McDermott. You start with 10 reps of crab walks (five in each direction), then go into walking lunges, handstands, and a stair run. If you don’t have access to a stairwell, you can hit an incline treadmill or jump rope.

Why It Works

McDermott’s body-weight circuits usually alternate upper and lower-body movements, then send you on a run, but the intensity of lunges and handstands (or handstand pushups, for the advanced) are amplified to a huge degree by the crab walks. “Your core is taxed the whole time,” McDermott says.

The Workout

Set a timer for 15 minutes and do the following circuit nonstop. Record your rounds completed.
