Hammer Strength Ground Base Combo Twist Parts & Diagram

Hammer Strength · Strength · Model GBCT

The Hammer Strength Ground Base Combo Twist is a plate-loaded rotational training machine with two independent movement arms that let users press and pull simultaneously while twisting through a standing, ground-based stance, combining the left and right twist movements into a single unit. It's a longtime staple in athletic performance facilities, and its simple all-lever construction with no cables or pulleys holds up well under explosive, heavy use.
