Your home fitness salvation has landed, in the form of the ultra-sleek Onyx C80 cross trainer. Cardio training is noted as notoriously tedious and dull, Marcyís Onyx range is designed to put an end to this.

Keeping you focused and motivated is key, 23 engaging programs can have you tackling hills one day and sweat dripping endurance challenges the next, with 16 levels of difficulties to harmonize with any fitness level. In conjunction with this, you can prop your phone or tablet on the console holder and blitz your workout in a flash.

Uncompromising quality is equally as important to consistent use. Onyx adapts perfectly to your body composition, thanks to 3-way adjustable oversized pedals combined with full length foam handlebars. The formula of a 7kg flywheel, 8' running disc, two-way bearing and solid black coated steel equals a smooth, reliable, robust fitness companion.
