Turn your walking routine into a complete workout with our 35-minute circuit.
Find a set of steps, then clasp your hands behind your back so your arms don't help you as you climb. Lean forward slightly with a straight back, and go up two steps at a time (skipping one in between) with your right leg. Step with the left, again skipping a step. Continue this lunge-like climb to the top, then walk down normally (without skipping any steps). Repeat for three minutes.
