Commercial cardio is where equipment budgets get spent fastest, so it is worth knowing which machines earn their footprint.
Curved treadmills are self-powered, so there is no motor, no power point and no top speed. The harder you run, the faster the belt moves. Ideal for sprints, intervals and classes, and almost nothing on them can break.
Motorised treadmills give you incline, programs and a cushioned deck. Still the right answer for steady-state running and for members who want a console.
Air bikes use fan resistance with moving arms, so resistance is unlimited and scales to the user. Minimal maintenance, brutal for finishers.
Ski ergs add a full-body pull that nothing else in the gym covers, in a very small footprint.
Stair climbers deliver high output at low impact, which suits older members and rehab work.
All of it is commercial rated and heavy. Freight is quoted per delivery, and pick-up from Morisset is free.
