صعود السلالم يبنى العضلات 

Stairs Build Muscle

Walking up the stairs builds muscle, which plays an important role in fat loss. The stairs work your quads, hamstrings, glutes, hip flexors and calves all in one workout. Although stairs only build your leg muscles, you lose belly fat efficiently because you're working some of the largest muscles in your body, including your glutes, quads and hamstrings. Exercises that build mass on your large muscles burn more calories while you're doing them and afterward. The more muscle mass you have, the faster your metabolism is, or the more calories you burn even at rest. By building muscle, walking up stairs also has long-term effects on fat loss by increasing your metabolism.

Stairs Burn Calories

Dr. Bryant from the American Council on Exercise said in an interview for an article for "The New York Times" that walking up stairs at a moderate intensity burns five calories a minute for a 120-pound person and nine for a 180-pound person. Climbing stairs on a stair treadmill for an hour burns about 660 calories for a 160-pound person, according to Mayo Clinic. For comparison, that's 350 more calories than you would burn walking in one hour, but you would burn about 200 more if you were running or jumping rope instead. Running upstairs instead of walking multiplies the caloric burn and the cardiovascular benefit, according to Dr. Bryant.
