Iso-Lateral Leg Curl

The Hammer Strength Iso-Lateral Leg Curl delivers a prone hamstring workout with precision-focused movement. The 4-degree outward angle of the work-arms ensures a natural, joint-friendly path of motion, allowing for smooth and controlled reps. The prone leg curl position promotes optimal hamstring activation by keeping the hips in a neutral position, minimising compensation and isolating the target muscles more effectively.  

Designed for athletes who demand performance, our iso-lateral leg curl machine provides balanced strength development through its independent work-arms, ensuring equal engagement on both sides.  

Dimensions (L x W x H): 69 x 57 x 41 in (175 x 145 x 104 cm)

Product Weight: 285 lb (129 kg)

A Prone Leg Curl That Feels Right

The two angled pads are designed for maximum comfort, even when going heavy. The peak at the hips takes pressure off the lower back, keeping the user stable and focused on their leg curl exercise. No distractions, no discomfort—just pure performance as they push through every leg curl with power and precision. Perfect for athletes who demand comfort without sacrificing intensity.  

Optimized Natural Movement

The 4-degree outward angle of the leg curl machine workarms keeps legs moving in a natural path, giving a smoother, more controlled rep every time. It’s built to match the way the body moves, reducing stress on the knees so the user can train harder, longer, and without unnecessary strain.

FAQ

The Prone Leg Curl positions the user face down for a stable, controlled movement that isolates the hamstrings with consistent tension—ideal for building strength and refining muscle balance. In contrast, the Kneeling Leg Curl introduces a more dynamic range of motion, engaging stabilisers like the glutes and lower back. Both are effective, but the prone version is designed for athletes focused on strict form and more muscle isolation. 
Yes, the Hammer Strength Iso-Lateral design allows for a single leg hamstring curl movement, ensuring balanced strength and symmetrical development. 
Yes, the leg curl machine's design adapts to users of various sizes, ensuring proper alignment and comfort during a workout. 
The angled pads peak at the hips to minimise stress on the lower back by avoiding hyperextension often associated with prone leg curls.
