The ONYX Split Squat is a premium plate-loaded strength machine engineered for targeted lower-body development and core stability training. Designed to support two foundational movements—Bulgarian split squats and sissy squats—it is ideal for commercial gyms and high-end training studios seeking versatile unilateral lower-body performance.

A 180° rotatable extended handle accommodates different shoulder widths and grip preferences for stronger control and higher training intensity under load. An ergonomic calf pad combined with a 6-position adjustable high-density foam roller provides stable support across a wide range of leg sizes and heights, helping users maintain ideal posture and alignment. The ergonomically angled front footplate reduces ankle strain and improves stance stability, while a high-precision linear guide system on the rear platform ensures smooth, stable movement throughout every Bulgarian split squat for accurate, consistent muscle activation.
