This exercise is great for stretching the extensor muscles in the forearm which is more like a temporary relief than a permanent solution.
Stand in relaxed position. Extend both your arms in front of you. Take your right arm and put it over your left arm and interweave your fingers together. With your left hand pull your right hand towards the ceiling. It is very important to keep your right arms locked in the elbow. Hold this stretch for approximately 30 seconds and repeat 3 to 4 tim
