Orangetheory has introduced a new AI-powered heart-rate tracking system called MaxHR to boost the personalisation and efficiency of members’ workouts.

Based on a proprietary algorithm, it records peak heart rate over a period of time to determine the member’s personal maximum heart rate. This data is used by trainers to improve the impact of sessions by identifying exactly when users should decrease or increase effort.

"For years, the standard of fitness heart rate tracking across the category has been an age-based formula that doesn't take into consideration other factors,” said Dave Long, co-founder and CEO. “MaxHR is a game changer in the industry, as it allows every member to know their personal statistics and shape their workout in a way that meets their individual needs."

Orangetheory’s approach to fitness is known for being accessible to people of all fitness levels due to its foundation of heart rate-based interval training based on effort. The trainer-led sessions alternate cycles of high-intensity work followed by lower intensity which allows the cardiorespiratory system to partially recover.

During an exercise session members spend time in each of the five heart rate zones with the aim of training for 12-20 minutes in zone four (orange) or five (red), which is the highest level. Classes mix up rowing, cardio (bikes, striders and treadmills), endurance and strength training

Orangetheory says the new algorithm is designed to evolve and become more accurate over time. For this reason, the MaxHR system is accessible to those who've completed 20 on-site classes with an OTBeat heart-rate monitor. Real-time updates will optimise the collected data and improve results.

Orangetheory’s system is based on post-exercise oxygen consumption (EPOC) where the body continues to use oxygen and burn calories for a period of time after the workout.

The chain has clubs in 24 countries and opened its 1,500 studio in Los Angeles last year. Despite the pandemic, the team signed up 500,000 new members in 2021 and launched a new flagship studio in Manhattan. The business runs via direct management and franchising.

UPDATE

Writing on 16 February 2023, Dave Long said: "Our mobile app now displays the most personalised performance summary for our members yet, providing detailed heart rate and performance data throughout their workout."

Long also said: "We also rolled out the next phase of our MaxHR updates. After just five workouts, hundreds of thousands of Orangetheory members (and counting) are now working in heart rate zones that are more accurate than ever before."
