Sit diagonally by a table. Bend your elbow and place it on the table. The elbow should be slightly in front of the body and slightly lower than your shoulder. Hold a dumbbell in your hand with your hand pointing straight up.
Keeping the elbow and shoulder in place in a controlled manner, lower the hand forward. Return to the starting position using support from your other hand.
Note: You can use a folded towel to elevate the elbow.
