Climbing is likely to cause pain in the buttocks, because the hip muscles mainly dominate the hip joint extension, back extension and external rotation activities, when climbing, because the hip joint must be strongly to straighten, to be able to force to climb and other sports, so there may be the following two situations that cause pain: first, may be climbing when the hip muscles are too hard, which leads to strains in the hip muscles. This situation will already occur during the climbing exercise, and the pain will be more obvious when you exert yourself; secondly, after climbing, the local lactic acid accumulates on top of the hip muscles, thus stimulating the muscles and causing muscle soreness, pain, weakness and other feelings, and the symptoms will naturally disappear after 2-3 days of rest.
