PRx Build Limitless Half Rack Functional Trainer

About PRx Build Limitless Half Rack Functional Trainer

Want cable versatility without giving up space? The PRx Build Limitless Half Rack Functional Trainer delivers a dual-sided cable system integrated into a USA-made half rack. Smooth aluminum pulleys, a 2:1 ratio, and dual 250 lb stacks let you move from bilateral to unilateral work in seconds—all inside a compact footprint.

Do more in less space

Skip separate machines. This system combines a full half rack with a commercial-feel cable trainer so you can hit pulls, presses, flys, rows, and belt squats from one station. It’s a clean layout that keeps your workflow fast and your floor clear.

• Overall: 97" H x 57" W x 34" D
• Trolley spacing: 45"
• Cable travel: 92.5"
• Included heavy-duty J-cups

Smooth resistance you can trust

Quality pulleys make every rep feel consistent. The 2" and 4" aluminum wheels reduce friction for controlled movement under load, helping you find the right path and stay in it from warm-up to top set.

• Aluminum pulley wheels
• Low-friction, controlled cable motion
• Durable cable: 4.8 mm with coating
• Built for frequent, heavy use

Fast adjustments for seamless sessions

Keep rest periods tight and supersets moving. Knurled handles and T‑handle pop‑pins let you slide each trolley to height quickly, then lock it in for the next movement. Unilateral or bilateral—switch on the fly.

• 2:1 pulley ratio for range and control
• Two 250 lb weight stacks
• Pop‑pin trolleys with knurled handles
• Adjusts cleanly for multiple users
