The Celsius AB1 Air Bike is a super effective workout machine for an intense cardio workout that'll help you burn fat and pour sweat quicker than a boxing session in a sauna. Simultaneously working your upper body as you push and pull the handles, and your lower body by cycling, the bike's fan naturally increases resistance the harder you cycle. One of the best HIIT workouts in town, the air bike is designed for short, intense workouts for beginners through to elite athletes. The four-way adjustable seat means you can get the right fit for your height while the wide array of metrics on the LCD monitor let you personalise your workout, monitor your stats and challenge yourself every session.
