Is stair climbing aerobic or anaerobic?

It belongs to aerobic exercise. When climbing stairs, you should concentrate and keep your eyes on the front; When going up the stairs, you should touch the ground with your forefoot and your hind legs straight. When stepping off the ground, you should pedal your toes hard, clench your fists or not, use your arms before and after, and pay attention to raising your head, abdomen and straightening your body. When you go downstairs, you should also land on your feet first, and then transition to landing on your feet with your arms placed at will. After climbing the stairs, you can "relax" your knees and have a local massage.
