Most workout injuries are soft tissue based and involve the muscles and connective tissue in the body. Most heal in a few weeks with rest of the affected part, the use of anti-inflammatories and ice, rehab work, and smart workaround training. Muscles will heal quicker than tendons and ligaments. Muscle spasms and strains are common and heal in a few days with proper care. Tendonitis and other similar injuries need the same healing protocol but can take longer to heal. Disc injuries to the spine heal slowly and, in some cases, never fully heal, leaving athletes with issue they have to work around for years.
