Sunil Sharma, fitness instructor, guides us on how to perform dumbbell kick back. Grab a dumbbell of reasonable weight in your right hand. Position your left hand and knee on a flat bench. Keep your right arm straight at your side. Slowly bend your lower right arm in, keeping your elbow out. While doing so, the position of your upper right arm must be parallel to the floor. The bend of your arm will exert tension on your triceps’ muscle. Return to the original position of the right hand and repeat the movement 10-15 times. You may perform the same movements with the opposite arm.
