The exercise works the pectoralis major as well as supporting chest, arm, and shoulder muscles such as the anterior deltoids, serratus anterior, coracobrachialis, scapulae fixers, trapezii, and the triceps.
Narrow, shoulder-width dips primarily train the triceps, with major synergists being the anterior deltoid, the pectoralis muscles (sternal, clavicular, and minor), and the rhomboid muscles of the back (in that order). Wide arm training places additional emphasis on the pectoral muscles.
The FO-09 outdoor exercise machine is unique for developing arm and back muscles. Makes doing chin ups or dips more accessible to beginners, but is also useful for seasoned users.
The FO-16 Seated Chest Press Machine is for working out the triceps, deltoids and pectoral muscles and makes outdoor strength training a simple, effective and safe.
