Back Extension Pin Loaded Machine | [T-MAX Series]

T-MAX Series Back Extension — Commercial Pin Loaded Machine

Lower-Back Strength | 100kg Weight Stack | 11-Gauge Steel | Model TY11

The T-MAX Back Extension trains the muscles most gyms leave to chance. Set the pads, brace the feet, and extend the torso against the stack — a guided, seated extension that loads the spinal erectors and glutes progressively, pin by pin, instead of leaving lower-back strength to bodyweight roman chairs.

Resistance is a 100kg pin-loaded weight stack — one pin moves the load between users in seconds. The frame is 11-gauge carbon steel at 232kg assembled, with polyurethane foam pads and premium PU leather built for all-day commercial use.

Key Features

• Guided extension arc — loads the lower back through its natural range, no balancing required
• Adjustable pads and foot support — sets the pivot at the hips for every user height
• Progressive pin loading — build lower-back strength in measured steps, rep by rep
• 100kg pin-loaded stack — one-pin weight changes, upgradeable to 140kg at $10 per kg on made-to-order builds
• 11-gauge carbon steel frame — powder-coated, with PU foam pads and premium PU leather
• Made to order in your colours — 16 frame and 12 upholstery options

Frequently Asked Questions

What muscles does the back extension work?
The spinal erectors first, with the glutes and hamstrings assisting — the pad placement keeps the hinge at the hips where it belongs.

Machine extension or roman chair?
Both have their place — the TY11 adds a pin-selected load to the movement, so progression is measured in kilograms instead of reps, and the guided arc suits users a free-hanging roman chair intimidates.

Can I upgrade the weight stack?
Yes — on made-to-order builds the standard 100kg stack can be increased to 140kg at $10 per kilogram. Get in touch to spec it.

Can I choose my own colours?
Yes — made-to-order builds come in your choice of 16 frame and 12 upholstery colours, with logo branding available. See the chart above.
