The Handle Bar 45
HB 45 is a 45 minute cycling session set to the beat of the MUSIC that gets you going. Weighted bars are used for a portion of the workout to incorporate upper body toning into the class. The format is designed to challenge your endurance and rid toxins from your system. Especially great for a Sunday evening restart. ;) The workout is infused with intensity, but still suitable for all skill levels. Get ready to SWEAT, INSPIRE, TRANSFORM, and RAISE THE BAR.
