The SportsArt N957 Leg Extension is a refined selectorized lower-body trainer from the elite Status Series, designed to isolate and strengthen the quadriceps with ergonomic precision and commercial-grade durability. A spring-assisted adjustable seat back ensures seamless customization for users of different heights, while the angled seat bottom minimizes lower-back strain for greater comfort. The leg pad adjusts easily, accommodating various limb lengths to secure proper leverage and optimal mechanics.

Achieve gradual and controlled strength gains using micro-loading increments of 3.5 lb and 6.5 lb, ideal for progressive training. Dependable, whisper-quiet performance comes from cold-rolled steel weight stacks with noise dampening, stainless steel guide rods for smooth, rust-resistant operation, and Kevlar-reinforced cables (2,200 lb tensile strength) that deliver smooth, silent motion. Designed for longevity and comfort, the upholstery is marine-grade and double-stitched, lining heavy-duty European-style cushions made to endure everyday commercial use.

Despite its robust build, the N957 maintains a compact and efficient footprint—measuring approximately 39.4" L × 51" W × 60.1" H and weighing 579 lb. It features a 220-lb weight stack, starts at 12.1 lb, and supports users of up to 500 lb. This machine delivers powerful and precise quadriceps development through industry-leading design and engineering.
