The Hammer Strength Ground Base Jammer is a great tool to build ground-based explosiveness. The open floor space is designed to keep the exerciser firmly planted on the ground in a natural position while maximizing power and explosiveness from the feet up. The angled handles allow the exerciser to adjust their grip to a desirable placement, resulting in a properly controlled motion.
