How to Do the Assault Bike Sprint
The assault bike sprint is an all-out burst on a fan bike that works your legs and arms together. The harder you push, the harder the fan resists, so it's a brutal, low-impact conditioning tool. It suits advanced athletes and lifters who want high-intensity intervals.
