The SportsArt G778 is an ECO-POWR™ Status Series stair stepper that does more than just challenge the body — it captures human exertion and converts it into usable electricity fed back to the grid. A natural stair-climbing motion, low step-up height, multi-grip racing handles, toggle speed controls, and 14 real-time readouts including Watts to Grid make it the most environmentally conscious commercial stepper available.
Power ECO-POWR™ | Speed Range 20–180 SPM | Step-Up Height Low Profile | Readouts 14 Real-Time | Programs Built-In |
ECO-POWR™ goes beyond self-powered — the G778 captures energy from every step and converts it into usable electricity that feeds back to the facility's power grid. Users can track their contribution in real time via the Instant Watt to Grid and Your Grid Wh readouts — a measurable, motivating reminder that their workout is making a positive environmental impact.
The G778 replicates the natural biomechanics of climbing real stairs — engaging glutes, quads, hamstrings, and calves through a full, functional range of motion with every step. A low step-up height makes getting on and off the machine safe and easy for users of all fitness levels, while the broad 20 to 180 steps per minute range accommodates warm-up walks to maximum-intensity conditioning.
Multi-grip racing-style handles with integrated contact heart rate sensors accommodate a range of hand positions — letting users shift their grip and posture throughout a session for comfort and variety. Toggle-based speed controls allow for precise, immediate speed changes on the fly without breaking stride or reaching for a console.
The backlit LCD display tracks 14 data points in real time — Heart Rate, SPM, Weight Loss Zone, Target SPM, Cardio Zone, Time, Floors, Your Grid Wh, Calories, Distance, Pace, METs, Cal/Hr, and Instant Watt to Grid. The Watts to Grid readouts are unique to ECO-POWR™ machines, letting users see their environmental contribution alongside their fitness data every session.
Built-in programs include Manual, Interval, Hill, Race, Fitness Test, and Heart Rate Control — covering everything from structured HIIT and hill training to heart rate-zone cardio and fitness assessment protocols. The 20 to 180 SPM speed range gives each program the room to challenge users at every fitness level.
At 473 lb, the G778 is built with the mass and structural integrity of a true high-traffic commercial machine. A safe-stop stair lock, adjustable step-up heights, an integrated 3-speed cooling fan, and the ECO-POWR™ grid-back technology combine to make it the most advanced and sustainability-focused stepper in the SportsArt commercial lineup.
