Impact+Shock Control (i+SC) — what it does for you

Running — even on a treadmill — can generate forces up to ~3× your body weight. i+SC absorbs and dissipates that force using eight elastomer absorbers plus Constant Speed Control for a smoother, lower-impact stride. The result: less joint stress and a more comfortable run or walk.

Customizable quick keys & training

The lower console includes dedicated quick keys for speed and incline. Save two custom speed settings and two custom incline settings — perfect for repeat interval workouts or instantly returning to your favorite walking/running intensities.

Entertainment & app connectivity

Choose the console that fits your routine: 16" or 10" Smart Touch for a tablet-style experience, or the efficient 9" Black Mask LCD. All consoles include GEMCONNECT Bluetooth/ANT+ so fitness apps can read speed, time, distance, and heart rate — letting you stream workouts, track progress, and sync to third-party platforms. Connect your phone, tablet, or cast to a TV; keep devices charged via USB and enjoy audio and HDMI inputs during long sessions.
