Roman Chair Hyperextension Bench Back Extension Trainer LKC‑904

Product Features And Advantages：

LKC-904 Roman Chair, also known as hyperextension bench, is a versatile body-weight strength-training apparatus. Fully welded from 50×50×1.5 mm square steel tubing, it comprises adjustable padded backrest, foam-covered calf-locking roller, foot supports and widened base. Multi-hole height adjustments fit users of various heights. Trainers execute hyperextension and torso side-flexion using body weight to strengthen lower-back, glute and hamstring muscles. Dumbbells can be held to increase resistance, and the bench can assist dumbbell shoulder press and shrug movements. Well-suited for home-fitness and small-studio environments.

Product Characteristics：

1.Robust Heavy-Gauge Square-Tube Frame: Welded 50×50×1.5 mm square steel tubing finished with electrostatic powder-coating for rust-proof and scratch-resistant performance. Solid frame tolerates regular body-weight and light-dumbbell workouts.

2.Multi-Position Hole-Based Adjustment: Backrest and calf-roller heights are adjustable via preset holes, matching different user heights and helping maintain correct exercise posture.

3.High-Resilience PU Foam Padding: Backrest and calf-roller surfaces are upholstered in wear-resistant PU leather over high-density foam, relieving pressure and resisting collapse during long training sessions.

4.Widened Base with Anti-Slip Feet: Reinforced triangular base plus rubber anti-slip feet stabilise the unit during exercise while protecting flooring.

5.Multi-Functional Training Capacity: Supports hyperextension for lower-back, oblique side-bends and glute-hamstring work; also enables dumbbell-assisted shoulder and trapezius drills.

6.Lightweight & Tool-Friendly Assembly: At 16 kg net weight, it is quick to assemble, disassemble, transport and store without occupying excessive floor space.

7.OEM Customization Available: Custom frame-coating and upholstery colours are offered alongside brand-logo printing for cross-border and bulk-order customers.

Product Parameters：

Notes: Place on flat hard ground. Lock adjustment knobs before use. Periodically inspect and retighten all machine screws.
