BURN high-intensity interval training (HIIT) is a group training workout that alternates between intense bursts of activity and fixed periods of less-intense activity or rest for maximum fat burning. BURN classes utilize the TRX Suspension Trainer, TRX Rip Trainer, Kettlebells, and much more to ensure you’re getting the best workout possible! Expect an intense 45-minute workout to test your endurance and strength. When registering, pick a one-time slot and you will have access to all classes with your registration. Your registration also includes all the virtual content.
