Again Thanks to My supporters Saucony Australia, Australian Sports Nutrition and REPS fitness Cairns and the Bowen athletic club Another drill that you can use for hammer. For this drill you can use either kettle bells or plates what ever you have available. You will require weight at both ends of the chain. The goal of this drill is to focus on your hips following the hammer around and it takes the arms out of it. try adjusting the length of chain and weight for different levels and ages.
