Try: Burpees
This exercise works your core, as well as your chest, shoulders, lats, triceps and quads, explains Michaels. Because burpees involve explosive plyometric movement, they’ll get your heart pumping too.
How to do burpees: Stand with your feet shoulder-distance apart and send your hips back as you lower your body toward the ground in a low squat. Then, place your hands right outside of your feet and hop your feet back, allowing your chest to touch the floor. Push your hands against the floor to lift your body up into a plank and then jump your feet just outside of your hands. With your weight in your heels, jump explosively into the air with your arms overhead.
Try: Mountain Climbers
Like burpees, Michaels is a fan of this moving plank exercise because it works your core, in addition to a slew of other body muscles.
How to do mountain climbers: Get into a high-plank position with your wrists directly under your shoulders. Keep your core tight, drawing your belly button in toward your spine. Drive your right knee toward your chest and then bring it back to plank. Then, drive your left knee toward your chest and bring it back. Continue to alternate sides.
