BONUS RIDE BONUS RIDE is a 75 minute class that combines our signature THREE15 class with the addition of a 20 minute “bonus” ride on the bike. THIRTY5 THIRTY5 is a 35 minute class that is a condensed version of our signature THREE15 class. It is a class that was created to give clients all of the burn of a signature class in a shorter amount of time. BASIC Basic is a class that we encourage all of our new clients to attend to gain a better understanding of the THREE15 method. This 45 minute class is a slower paced version of our signature THREE15 class that will help you perfect your form. STRENGTH45 STRENGTH45 is a 45 minute rhythm-based class that begins on the bike followed by strength training on the floor with heavier weights. EXTEND45 EXTEND45 is a 45 minute class focused on stretching, flexibility, and mobility while improving overall strength.
