Wrist strength

What is wrist strength?

It is commonly referred to as “wrist strength,” but in reality, the wrist is made up of bones, joints, and ligaments, as shown in the figure, and there are no muscles there.

Strictly speaking, it is the “strength of the forearm muscles” because it is the forearm muscles that control the movement of the wrist.

The forearm muscle group is composed of more than 20 muscles and performs complex wrist movements.

These are classified into “forearm flexor muscle group” and “forearm extensor muscle group”.
