Part 4: Exercises – Shoulder strengthening (flexion, abduction, and extension)

Isometric exercise is a type of strength training that involves contracting a muscle without visibly moving the joint. Isometric exercise is done in one position, keeping the joint stable instead of moving it.

Isotonic exercise is a form of strength training that involves contracting a muscle while moving the joint through its range of motion. This can be done using weights, rubber bands, or your own body weight.
