Why: Tones your rectus abdominis, the long muscle that runs from your ribs to your pelvis, to give your abs super definition.

How: Lunge with left foot in front and right foot about 2 feet behind it, arms bent at sides. Keeping left knee bent and torso still, lift right knee toward chest and lower, swinging arms back and forth. Switch legs and repeat.
