R4 Unit PRO All-in-One Trainer

The R4 Unit PRO All-in-One Trainer brings commercial-grade training into your space. This heavy-duty steel system merges a Smith machine, power rack, and dual-stack functional trainer into one complete setup.

Built from 3" x 3", 11-gauge steel with dual 200 lb weight stacks, it delivers versatile training across multiple disciplines. The adjustable 2:1 pivot arms excel at functional and isolation work, while fixed 1:1 high/low center pulleys handle heavier compound movements like lat pulldowns and rows.

The integrated Smith machine features an 58 lb linear-bearing bar with 18 positions and 1,400 lb capacity. Its low position descends to just 10" from the floor, opening options for deadlifts, hip thrusts, and floor presses. The 47" internal width stays fully accessible with outside-mounted hooks.

Engineered for performance: 4" commercial aluminum pulleys with sealed bearings, 98" cable length for full range of motion, and a 90" pull-up bar accommodate all users. Weight stacks increment by 11 lb and accept Olympic plate adapters for added load.

Integrated storage keeps your space organized with four plate pegs and a 24" x 41" rear pegboard. An external squat rack option extends free-bar training possibilities.
