The Sole ST90 treadmill has a slat belt design, a 2 Horsepower AC motor, and 10.1” touch screen display. The ST90 works with Sole’s fitness app STUDIO, which offers more than 3,000 classes to use with and without your treadmill. You can also use the treadmill without the STUDIO app, as there are multiple pre-programmed workouts such as standard, custom, and heart-rate training.
The ST90 has a 20-inch-by-60-inch running belt. Sole claims that the slat belt design increases safety and comfort while decreasing wear and friction. The treadmill has a speed range of 0-12.5 MPH and 15 incline levels. The 10.1-inch touchscreen display can stream workouts or your favorite shows via screen mirroring technology. You can also play your phone’s music through the treadmill speakers. The treadmill has both grip and telemetric heart rate capabilities but does not come with a heart rate monitor chest strap.
The ST90 has an integrated tablet holder with a USB port for charging your devices. There aren’t pre-programmed quick adjustment buttons, but there are increase and decrease buttons on the inside of handrails.
There are very limited reviews but they are positive. Users liked that the treadmill adjusted speed and incline quickly but wished there were quicker speed adjustment buttons. They also found the treadmill sturdy and quiet.
