I Tried Orangetheory's New Technology With the Apple Watch, and It's a Game Changer

As one of the world's fastest-growing fitness studios — there are 1,300 locations in over 23 countries — Orangetheory Fitness has a loyal following of people who are dedicated to the hour-long HIIT cardio and strength-training workouts. And while OTF has its own proprietary technology with the use of heart rate monitors for you to track your heart rate throughout the workout and earn Splat points (the amount of time your spend with your heart rate in the orange and red zones, or approximately 84 to 100 percent of your max heart rate), the company said the number one request they got from customers was the ability to use their Apple Watches to sync up to the class. Now, Orangetheory has delivered.
