BodyKore GR617 Selectorized Rotary Torso The BodyKore GR617 Selectorized Rotary Torso trains the rotational musculature of the core — external and internal obliques — through a controlled, guided spinal rotation arc that loads the twisting movement pattern directly. Unlike cable rotation exercises where stabilization demands limit usable load, this machine eliminates unwanted movement planes and allows progressive overload in the rotation pattern alone. The bilateral range of motion provides full training of both sides from a single seated position.
