Only available from Hammacher Schlemmer, and using no electricity, this is the compact trainer that simulates cantering on a horse to strengthen and tone the core muscles. Exercisers sit on the padded saddle, rest their feet on a rubberized bar, grasp the padded adjustable handlebar, and shift their weight backward to put the device’s drivewheel in motion. As the saddle rotates at a moderate 40 rpm or less, it requires the rider to engage lumbar muscles, abs, glutes, and thighs, building core strength to help prevent back injuries and improve balance and posture. A 10-minute session can burn as many calories as 200 situps or a one-hour walk. Because it doesn’t require a power cord, the core exercise machine can be used anywhere, and it weighs half as much as many core trainers, allowing it to be moved easily between rooms or stowed away between workouts. The seat and footrest can be raised or lowered. Supports up to 250 lbs. Assembly required. 43" H x 22" W x 28" D. (35 lbs.)
