Exercise is recommended to alleviate musculoskeletal problems.

It is possible to exercise voluntary muscles but not involuntary muscles.

Explanation:

Musculoskeletal problems are disorders and injuries that affect any of the musculoskeletal system of the body, such as the muscles, tendons, ligaments. Examples of musculoskeletal problems include tendonitis, ligament sprain, mechanical back syndrome, etc. Various risk factors have been shown to cause these problems which may be ergonomic or individual-related risk factor. These problems often develop when the body system is unable to recover from fatigue, leading to musculoskeletal imbalance or time.

Regular exercise has immense benefits on the musculoskeletal system as it helps to alleviate musculoskeletal problems by increasing the size and strength of the muscle fibers, ligaments, tendons, improving the muscle efficiency of burning energy, as well as improving the supply of blood to skeletal muscles.  

Having regular and appropriate exercise will reduce your chances of developing musculoskeletal problems as you age.

Involuntary muscles are the cardiac muscle found in the wall of the heart and the smooth muscles found in the walls of the digestive system. These muscles work continuously and cannot be controlled consciously. Hence, they cannot be exercised like the voluntary muscles. The voluntary muscles are the skeletal muscles which can be controlled consciously, hence, they can be exercised.
