15-Minute Stairs Workout
Stand on the floor facing the stairs.
(A) Place your left foot on the far-left end of the second step.
(B) Follow with your right leg, bringing it to the far-right end of the fourth step. Continue climbing, taking the stairs two at a time with wide steps while keeping your head up. To boost the calorie burn, swing your arms and engage your abdominals as you go. After reaching the top, walk back down. That’s one rep. Do one more.
