The Nordic Track SE5i elliptical cross trainer allows to work both lower body muscles (legs, thighs & buttocks) & upper body muscles (biceps, triceps, abdominals, pectorals) & features a 16kg (35.3lbs) inertia enhanced flywheel for smooth performance. Featuring 35 challenging programmes & 24 digital levels of SMR Silent Magnetic Resistance to let you vary the intensity of each session, this sturdy machine offers plenty of ways to boost your workouts. For a comfortable ride, it has a stride length of 16'' (41cm) & there is an adjustment knob located on the workout arms to let you adjust the motion of the pedals should you wish to alter the path of the stride & engage different leg muscles. The SE5i is compatible with i Fit Coach BLE technology to give you access to hundreds of energizing interactive workouts designed by world-class trainers & provides feedback on key training data thanks to a clear 5'' backlit i Fit® display. To maximize results by targeting a specific heart rate zone measure your pulse using hand pulse grips or a Bluetooth® Smart wireless receiver with an optional chest strap. Plus, the elliptical enables you to enjoy your favourite shows, movies & music with an integrated tablet holder that allows for placing a device above the console not to interrupt your workout.
