Iso-Lateral Leg Extension

The Hammer Strength Iso-Lateral Leg Extension is built to strengthen one of the most fundamental movement patterns—knee extension. Whether sprinting, jumping, or powering through change of direction, explosive quad strength is critical. This plate loaded leg extension machine isolates each leg independently, reinforcing balance, control, and unilateral strength. 

It's not just about building muscle, it's about building the kind of force that drives athletic performance and protects joints through every stride, lunge, and lift in sport and life.

A Leg Extension That Feels Right

The two angled pads lock the user in for maximum comfort during a leg extension workout, even when going heavy. The angled back pad and seat belt keep the athlete stable and focused on what muscles leg extensions work. No distractions, no discomfort—just pure performance while pushing through every set with power and precision. Perfect for athletes who demand comfort without sacrificing intensity. 

Optimized Natural Movement

The 4-degree outward angle of the work-arms keeps legs moving in a natural path during each leg extension exercise, giving a smoother, more controlled rep every time. This design addresses concerns about whether leg extensions are bad for knees by matching the way the body moves, reducing stress on joints so the user can train harder, longer, and without unnecessary strain.
