ONYX Bicep / Tricep Machine

The ONYX Biceps Curl / Triceps Extension combines two essential arm exercises within one compact commercial machine. The adjustable movement arm allows users to transition between controlled biceps curls and triceps extensions, providing targeted training for both sides of the upper arm without requiring separate equipment. The angled arm pad supports consistent elbow positioning and helps minimise unwanted shoulder movement throughout each repetition. An adjustable seat allows users of different heights to align comfortably with the machine’s pivot point, while the ergonomic handles provide a secure grip across both movements. Smooth selectorised resistance delivers consistent loading and allows quick weight adjustments between sets. Built with a heavy-duty commercial frame, premium upholstery and durable components, the ONYX Biceps Curl / Triceps Extension offers versatile, space-efficient arm training for commercial gyms, studios, hotels and professional training facilities.
