The first one, for example, you can practice sitting posture with the wrist and palm flexed. During the practice, you can sit in the chair again, put your forearm on the table, and then take a heavy object in your hand as a load, such as a dumbbell. Then keep this action for 5 seconds when your wrist flexes to the maximum extent, and then slowly put it down. Wrist-palm flexion sitting posture is mainly to strengthen the muscle strength of your forearm wrist flexion muscles.

Second, you can do stretching exercises in practice. Stretching the wrist in the same direction as the back of the hand is called wrist stretching, which can exercise the forearm extensor of the body.
