Health tech company Ultrahuman, makers of the Ultrahuman Ring Air and Ring Pro, launched a partnership with group workout brand Les Mills on Wednesday. Together, the companies created the Les Mills PowerPlug in the Ultrahuman app, which recommends workouts based on data collected by its smart rings, like sleep, recovery and cycle phase. 

Traditionally, when your smartwatch or ring tells you that your body is fatigued and that you should take it easy during your workout, it doesn’t provide the workout. With this new integration, the Les Mills PowerPlug offers expert-led, on-demand workout videos that take your current health status into account and help prevent overtraining.

“With Les Mills, we're closing the loop -- your ring doesn't just tell you how recovered you are, it tells you what to do about it. The right workout, at the right intensity, every day. That's what training smarter actually looks like," Mohit Kumar, CEO of Ultrahuman, said in a press release.

How the PowerPlug works

Upon downloading the Les Mills PowerPlug, Ultrahuman Ring users will be asked to choose their ideal training days, session length and a fitness goal from the following: cardio, strength, flexibility or general fitness. Going forward, the app’s home screen will then recommend two to three daily workouts based on your health data, along with a quick workout shortcut. 

You’ll also have access to Les Mills’s entire workout catalog, which you can sort by goal, program or duration. Yoga, strength, HIIT and stretching are just a few examples of the type of exercises you can perform.

To select your workout recommendation, Ultrahuman uses its Dynamic Recovery score, a percentage from zero to 100 that symbolizes how prepared your body is to take on the day. It takes into account your sleep, temperature, stress rhythm, resting heart rate and heart rate variability and can change throughout the day with movement, naps and non-sleep deep rest like breathwork.

The Les Mills PowerPlug will also adapt its selections based on a user's menstrual cycle. If they’re in a phase with more energy, such as the follicular or ovulatory phases, they'll be advised to try a more intense workout. Low-energy luteal and menstrual phases will correlate with workouts that prioritize recovery, like yoga. During menstruation, high-impact workouts that are tough on the pelvic floor will be avoided. 

Once you complete your workout, you can then view your workout stats (duration, heart rate zones and calories), movement score, muscle group radar chart, daily goal progress and a post-workout recovery prediction that estimates your readiness for the next day.

The Les Mills PowerPlug price

Global Ultrahuman Ring Air and Ring Pro users can now purchase the Les Mills PowerPlug for $12 per month or $100 per year. 

Due to a patent lawsuit with Oura, makers of the Oura Ring, the Ultrahuman Ring Air was previously banned in the US. However, in March, Ultrahuman launched its Ring Pro, which the US Customs and Border Protection approved for sale in the US. It is currently available for preorder and will start shipping on May 15. With a charging case, it costs $479.
