The Hammer Strength Ground Base Jammer is a legendary, plate-loaded machine designed to build explosive, full-body power by mimicking athletic, ground-based pushing movements. It strengthens legs, hips, core, and shoulders through a converging, multi-joint motion, making it a staple in sports performance facilities for enhancing on-field power.

With an adjustable bench this machine can be used as a Incline bench press and a shoulder press depending on the degree that the bench is set at.
