Hand
Test: "Small Fist"
Bend all fingers only at the joints in the middle and at the end of the fingers, then stretch them out again (like a rake).

Exercise 1: "Big Fist"
Bend all fingers at all three finger joints, then stretch out the fingers.

Exercise 2: "Spread hand"
Spread all the fingers outward from the middle finger and then back.

Exercise 3:
Stretch a small rubber band from the thumb consecutively to all the other fingers, spreading each of the fingers as far as possible and then closing them again. Alternatively, spread the fingers as far as possible to create tension and then hold the position for 10 seconds.

Exercise 4:
Take a tennis ball (better than a golf ball in this case!) and squeeze it firmly. Hold the tension for a few seconds, then relax the fist and spread your fingers. Repeat the exercise 10-20 times per hand.

Exercise 5:
Roll a tennis ball over a tabletop with the palm of your hand, changing the direction and the amount of pressure.
