to Strengthen Playing Hands
I am not a trained medical professional, so as with any exercises, consult a physician before starting any routine.
We need to build strength in our fingers and wrist and one way we can do this is through dumbbell exercises. I would start out with the smallest dumbbell weight you can find (1-2 lbs) and work your way up to heavier ones. It is unlikely your fingers have experienced this type of exercise so take it slow then move to something more so as not to injure yourself.
To start out with lay the dumbbell on a table or flat surface. Place your hand flat on the table underneath the dumbbell. Curl your fingers up and then lay them flat again several times. When you feel that you can do this without any strain on your muscles, move to a higher weight or more repetitions.
Finger Exercise: To begin, lay the dumbbell on a table or flat surface. Place your hand flat on a table, palm up, underneath the dumbbell. Curl your fingers, not wrist. Next, using your fingers, push the dumbbell up then lay flat again. Do this several times. When you feel you can do this without any strain on your muscles, move to a higher weight or more repetitions.
Wrist exercise: Hold your hand flat with the dumbbell in the palm of your hand and curl your wrist upward and then release it downward. Do this 3-5 times every day.
