The advantages of using a chest arm expander are:
- Biceps is a muscle with two muscular heads whose main function is bending the arm.
- When flexing the arm, another muscle, the upper arm, is also used.
- The upper arm can be fully exercised only when performing forearm lifting exercises.
- In addition, the major flexor muscles in the upper forearm are also involved in flexion arm movement, and the flexors are strengthened by the side tension of the tensioner.
