Muscle strain is an injury caused by sharp contraction or excessive stretching of muscles during exercise. This is easy to happen in pull-ups and sit-ups. After muscle strain, there is a sharp pain at the strain site, and the rope-like lump formed by muscle tension can be felt by hand, with obvious tenderness, local swelling or subcutaneous bleeding, and the activity is obviously limited.
