Here are a few that can be done regularly: 1. Wrist Extension and Flexion - Gently bend your wrist backwards (extension) and then forward (flexion) while keeping your arm straight.

The elbow should be flexed at 90 degrees, and place the opposite hand on the forearm to stabilize the arm. Grasp a dumbbell in the working hand and bend your wrist down.

Wrist extension can be assessed basically by putting the hands together in a “prayer” position and pulling the hands down toward the waist.

Pakistan off-spinner Saeed Ajmal failed his biomechanics test in Brisbane because his average elbow extension was more than double the 15 degrees allowed by the ICC.
