Now that your body is warm, get ready to kick things up a notch with this pushup variation that works your chest, arms, abs, and legs.
How to do it: From a kneeling position, press your hips up and back behind you so that your body resembles an upside down "V." Bend your knees and press your chest further back towards your thighs, stretching shoulders. Shift your weight forward, extend your legs, and lower hips, bending elbows into a full pushup (try to tap your chest to the ground if possible).
Press your hips back up and return to "V" position, keeping knees bent. Power back and forth between the pushup and press back position as many times as you can for 1 minute.
