Iso-Lateral Leg Curl

Name: Plate Loaded Iso-Lateral Leg Curl
Brand: hammer strength

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, minimizing 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.

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.
