The Ultimate Pro Functional Trainer

We engineered the GravoMax GM280 Pro Functional Trainer to give you the ultimate hybrid training experience. We combined the massive stability of a commercial squat rack with the buttery-smooth performance of an elite cable station. The heavy-duty 75×75mm steel frame (3mm wall thickness) provides a rock-solid foundation for heavy squats, presses, and pull-ups.

What truly sets the GM280 apart is the advanced cable system. You can choose between dual 75kg or dual 100kg steel weight stacks to perfectly match your strength level. We implemented a highly versatile 2:1 weight stack ratio across both options. This ratio gives you perfect, extended cable travel for functional training and explosive movements. Every detail matters on a pro-level machine. We fully lined all contact surfaces on the trolleys and J-cups with premium UHMW plastic. This protects your barbell knurling and the rack’s matte powder-coated finish from scratches during heavy daily use.

Elite Component Upgrades

Smoother Than Butter Pulleys: We used black anodized aluminum pulleys paired with precision bearings and aircraft-grade cables. This creates an exceptionally smooth, fluid feel that you will notice on every single rep.
Guide Rods & Stabilizers: Solid steel guide rods paired with precision-machined aluminum guide rod stabilizers ensure tight tolerances, heavily reduced friction, and noticeably quieter operation.
Premium Trolley Design: A fully knurled handle provides a secure grip for height adjustments. The oversized pop pin locks firmly into your upright for fast, confident changes. Hard-chromed shrouds protect your fingers and attachments.
Ready to Lift: The package includes a pair of premium silver alloy pulley handles, allowing you to start training immediately.

Frequently Asked Questions (FAQ)

Which weight stack option should I choose (75kg vs 100kg)?

The 75kg option (per side) provides plenty of resistance for functional training and most athletes. If you are an advanced lifter planning to do heavy seated rows or lat pulldowns using the cable system, we highly recommend upgrading to the 100kg stacks for maximum strength gains.

What does a 2:1 weight stack ratio mean?

A 2:1 ratio means that moving a 10kg plate provides 5kg of actual resistance at the handle. This setup doubles the cable travel distance, making it perfect for explosive functional movements and long-range exercises.

Is it stable enough for heavy barbell training?

Yes. The 75 × 75mm / 3mm steel frame, reinforced front support bracing, and massive steel weight stacks keep the station completely planted during heavy squat and press sessions.

Can I add more attachments later?

Yes. The GM280 is part of our modular ecosystem. It is fully compatible with our GravoMax GM Add-ons. We highly recommend using our GM system to guarantee a perfect fit.
