Running is a primarily forward motion, but there is significant lateral motion generated as moving one leg after the other in the gait. Hence lateral stability and strength plays a very important role in controlling the body through the gait. At RunMechanics we observed that a lot of runners don’t have enough lateral stability which causes significant sideward motion during the gait, and more specifically trunk bend at mid-stance. We have also observed many runners' low on pelvic rotation and could not utilize it optimally for efficient stride.
Axe Chops is an excellent workout to strengthen the core required for lateral stability and also to improve pelvic rotation.
As the name suggests, it is cutting the wood with an axe and the flow of the workout is in the similar manner. This workout requires dumbbells. Use a weight of 5-7.5 Kgs to start with.
Include it as part of strength training, with 2-3 sets of 20, one can gradually increase the repetitions and also the weight of the dumbbell.
