Premium Isolation. Precision Engineering. Built for Serious Hamstring Development.

The OnHim Seated Leg Curl is engineered to deliver unmatched hamstring isolation with zero compromise in biomechanics, stability, or user fit. Every adjustment point has been designed far beyond industry norms, ensuring that athletes of all sizes can lock into the machine with perfect alignment and generate maximum tension through the full range of motion.

This model eliminates the common weaknesses found in traditional seated leg curls—seat sliding, unstable positioning, limited pad adjustability, bent lever arms, and inconsistent load curves—while offering the durability and smoothness Newtech is known for.

Whether outfitting a professional facility or a private high-performance training room, this machine guarantees a premium experience for strength athletes, physique competitors, and everyday users alike.

Key Features

Industry-Leading Adjustability for Perfect Alignment

12-Position Upper Thigh Pad (double the industry standard):

Provides micro-adjustability so users never feel “in-between” settings. Locks the femur firmly in place, maximizing hamstring recruitment and eliminating unnecessary hip movement.

8-Position Backrest Angle Adjustment:

Enables athletes to fine-tune torso alignment for optimal pelvic position and peak contraction.

8-Position Fore–Aft Seat Slide:

Allows the entire seat to glide forward or backward for precise hip-to-knee alignment, ensuring every user—short or tall—can set up perfectly.

Fully Adjustable Ankle Positioning

Multi-Rotation Ankle Pad on Slider Rail:

Twists and moves along a numbered slider to match every shin length, ankle position, and foot angle, ensuring a comfortable but locked-in curl movement.

Enhanced Stability and Power Output

Integrated Seatbelt:

Anchors the athlete’s hips to the pad, preventing the pelvis from lifting during heavy or high-rep sets. This eliminates momentum, forces pure knee flexion, and dramatically increases hamstring activation.

Reinforced Curl Arm Support Bar:

The curling lever is equipped with a secondary reinforcement bar to prevent long-term bending or flex—far surpassing typical commercial leg curl durability.

Smooth Resistance & Long-Term Reliability

Advanced Cam-Driven Load Curve:

Designed to match the natural strength profile of the hamstrings, maintaining tension throughout the entire movement.

Commercial-Grade Construction:

Heavy-duty steel frame, oversized pivot points, and anti-corrosion hardware for years of performance in high-traffic facilities.

Weight Stack

125 kg Weight Stack (customizable):

Perfect for athletes who train with progressive overload or heavy concentric work. Optional custom stack upgrades available for facilities needing more resistance.
