Running Stairs

Rocky Balboa's got nothing on you. You don't need to train for a prizefight to get in a good leg workout. Today, skip the elevator and take the stairs to activate your glutes and stretch your hamstrings. Think "Beast Mode" the next time you're tempted to take the escalator and choose the stairs instead. For a greater challenge, take two stairs at a time. The body mechanics of a brisk stair run mimic static lunges and you get all the same fitness benefits.
