Description

Kinta SAS Series Multi Back Extension

The Kinta SAS Series Multi Back Extension is a selectorised, multi-functional strength machine engineered for serious posterior chain development — targeting the erector spinae, glutes, and hamstrings with a stable, controlled hinge pattern.
Built with precision craftsmanship and a high-smoothness pulley system, the RE8040 delivers fluid motion and strong stability even under heavier training loads — making it a great fit for commercial gyms, performance facilities, and PT studios that want a back extension solution that feels premium and adjusts quickly for different users.
Adjustability is the big win here. The 9-position air-assisted thigh pad makes it easy to fine-tune body position and training angle without the usual fiddly setup. Dual side handles add support during setup and transitions, making it safer and easier to get in and out of the machine — especially when fatigue kicks in.
For lower-body positioning, the RE8040 includes a 6-position adjustable high footplate to suit different leg lengths and allow comfortable knee flexion while driving better glute engagement. The front calf pad adds even more versatility with 5 levels of angle adjustment, letting you change hinge angles to cover a wider range of posterior chain exercises — from spine stabilisation work through to lower-body hypertrophy-focused training.
The wide dual-angle foot platform includes both flat and inclined anti-slip surfaces for ergonomic foot placement and better stability. It’s especially helpful for users with limited dorsiflexion, making it easier to get set and stay locked in.
Finally, a front-positioned load handle provides a controlled, practical way to increase resistance, helping users progress intensity safely and effectively.

Key Features

  • Posterior chain focus
    Targets erector spinae, glutes and hamstrings with a stable, controlled movement pattern.
  • 9-position air-assisted thigh pad
    Quick, precise adjustment for different body types, postures and training goals.
  • 6-position adjustable high footplate
    Suits different leg lengths and supports comfortable knee flexion with targeted glute activation.
  • 5-level adjustable calf pad
    Multiple hinge angles to expand exercise variety and fully load the posterior chain.
  • Dual-angle wide anti-slip foot platform
    Flat + inclined surfaces for better access, ergonomic setup and improved stability.
  • Front load handle
    Controlled resistance loading for safer intensity increases and stronger muscular stimulation.
  • Smooth pulley system + commercial stability
