90 Seconds of Assault Bike
Coaching Note: You don’t have to do the double-unders quickly, but you will need to do them in a fatigued state. Push hard on the 90 seconds to rack up as many calories as possible…then transition and get the double-unders done so that you can rest a bit before your next interval. Consider doing Fitness Part B instead if the double-unders are going to give you issues.
