Icon Health and Fitness has announced that iFit, the patented connected fitness platform that powers its NordicTrack, ProForm and Freemotion equipment, is about to release the iFit Active Pulse, a new patent-pending technology that allows a member’s heart rate to automatically tailor the treadmill’s speed and incline. The new technology uses complex algorithms that gradually “learn” unique behavioral patterns over time in order to automatically adjust iFit’s library of workouts to the user’s individual fitness level and goals. Without this technology, a person can only manually monitor and decide to adjust their effort in order to remain in an optimal heart rate zone. Heart rate is impacted by daily variables like stress or sleep, which means that the effectiveness of a given workout also varies from one day to the next based on heart rate performance. The new iFit Active Pulse is also compatible with third-party devices from brands such as Polar, Garmin, Wahoo and Whoop. It will be available through an automatic software update in January on all iFit-enabled NordicTrack, ProForm and Freemotion treadmills. The feature will then become available for rowers, stationary bikes and ellipticals soon after. Members can connect with iFit workouts in English, Spanish, French and Mandarin Chinese, with more languages due to be added in 2021.
