Join Runners From All Over the World
Zwift is a massively popular training program and multi-player running video game. Users can interact with each other while competing in a virtual world.
If you’re training for a 5K or marathon, or simply want the motivation of running live with a community, Zwift is for you.
The 7.8 AT Studio Treadmill directly connects to the free Zwift app so you can join the Zwift community and run in one of over 200 virtual races a day.
Rapid Sync Motor Perfect For Interval Training
Power your workouts with a 4.0 Continuous-Duty Horsepower motor and 500 lb thrust incline motor. Together, they create the most responsive drive system available in a treadmill. That means faster changes and a smoother, more efficient run.
The Johnson Digital Drive System featuring Rapid Sync™ Technology ensures no lags or delays between speed and incline changes. It responds 33% faster than other treadmill motors, so you’ll never fall out of step with a fast-paced interval running class.
Maximum Results Minimum Time
Achieve maximum results in less time with our 20-minute high-intensity interval training workout, proven to burn up to 27% body fat in just eight weeks.
Sprint 8 is more efficient than a basic HIIT workout because it engages fast-twitch muscle fibers and naturally stimulates Human Growth Hormone (HGH). This triggers a response in the body that melts fat, encourages lean muscle mass and increases energy.
