Watson Single Stack Leg Extension

The Watson SS Leg Extension is a purpose-built quad isolation machine, extensively developed to deliver the best possible quad activation and training experience for every user. Designed as a core piece of any strength training setup, it combines a heavy-duty single-stack build with an angled, free-pivoting seat design to maximise range of motion and comfort throughout the movement.

A cam-profile resistance system paired with a large counterweight delivers a smooth, consistent resistance curve through the full range of motion, while multiple adjustment points let it accommodate a wide range of user sizes. The open-sided frame design makes entry and exit easy, and a seatbelt with large handles keeps the user secure and stable under load. Built in Great Britain with a lifetime frame warranty, it's designed for long-term, heavy commercial use.
