Air stride cushion, heart rate monitor, 8 half-hour programs (4 cardio and 4 strength training), approximately 10 % slope, and up to 10 mph. Speed change is simple, simply push the speed you want to go, no irritating increase/decrease buttons. Fold to save space. Have placed on less than 300 miles because I purchased it from Play it once more sports 2 years earlier. Downsizing and do not have space for it. You choose up. Thanks!
