This can be done at home, in your office, apartment building, or on stair-climbing machines in the gym.
Climbing two steps at a time is good for building the quadriceps (thigh muscles) and the gluteus (butt). Going down steps builds strength in the quadriceps and to a lesser extent, the hamstrings.
See how many places you can find stairs and challenge yourself to climb more each day.
