The SB Fitness CT400 is a self-generated, curved commercial treadmill built for serious training in home and facility settings. Because the belt is powered entirely by your stride, the treadmill responds instantly to changes in pace — from a steady walk to an all-out sprint — with no top-end speed limit imposed by a motor.
The curved running surface encourages a natural, mid-foot stride and engages your posterior chain throughout the workout, making it a strong fit for running, walking, sport-specific drills, and HIIT sessions. Three resistance levels let you scale the challenge, whether you're focused on conditioning, sprint work, or higher-effort interval training.
A front-mounted digital display keeps key metrics in view at a glance, including time, distance, speed, calories, and total miles of use. Side handrails offer stability when starting, stopping, or stepping on and off, while built-in wheels and a transport handle make it easy to reposition the treadmill when needed.
Constructed from steel and finished in black, the CT400 supports users up to 450 lb and is backed by a 5-year manufacturer warranty.
