[London, 22 April 2026] — Ultrahuman, the health technology company behind the Ultrahuman Ring, today announced a global partnership with Les Mills, the global leader in group training.
The collaboration brings Les Mills' studio-quality workouts directly into the Ultrahuman app, using continuous biomarker data from the Ultrahuman Ring to recommend the right workout based on each user's individual recovery, sleep, and even cycle phase. This includes the new Ultrahuman Ring PRO, which offers category-leading 15-day battery life and a redesigned heart-rate sensing system for even greater accuracy.
Today, most wearable users face a disconnect – their wearable tells them they're under-recovered, but their training plan carries on regardless. The result is overtraining when fatigued, undertraining when ready, and a persistent gap between wearable insights and real-world training decisions. The Les Mills PowerPlug closes that gap.
What’s more, according to the Les Mills 2026 Global Fitness Report, 90% of people prefer workout sessions led by real instructors rather than AI-generated plans.
This integration is designed around exactly that – human-led coaching, powered by real-time biometric insight.
When Ultrahuman Ring users first download the Les Mills PowerPlug, they choose a personal fitness goal (Strength, Cardio, Flexibility, or General Fitness), preferred training days per week, and session length. Every recommendation adapts automatically based on recovery, sleep, and cycle phase data from the ring.
The integration gives Ultrahuman Ring users access to Les Mills' diverse catalogue of video workouts — including HIIT, BODYPUMP™, strength, yoga, stretching, and recovery sessions — led by expert Instructors and available on demand.
Each day, the home screen shows two to three recommended Les Mills workouts matched to the user's current status, a Quick Workout shortcut, and access to the Les Mills catalogue to browse by programme, duration, or goal.
The recommendation engine maps Ultrahuman's Dynamic Recovery scores directly to workout intensity and type. Unlike static overnight recovery scores, Ultrahuman's readings adjust dynamically to movement, non-sleep deep rest (including breathwork), and naps.
A well-recovered user with elevated heart rate variability and low resting heart rate might see BODYPUMP™ or BODYCOMBAT™ at the top of their feed. On the other hand, a user with accumulated sleep debt, elevated body temperature, increased resting heart rate, or low heart rate variability would be guided toward yoga, BODYBALANCE™, or a gentle mobility session instead.
For women who track their cycle, Les Mills PowerPlug adjusts recommendations based on menstrual phase. High-energy phases (follicular, ovulatory) unlock intense workouts like GRIT and BODYCOMBAT™, while luteal and menstrual phases automatically shift toward recovery-friendly content like BodyBalance and Yoga – with hard safety filters that remove high-impact or pelvic-floor-challenging workouts during menstruation.
What differentiates the Les Mills PowerPlug from watching Les Mills content on any other platform is what happens after the session ends. The ring stays on during every workout, and on completion, it shows:
The result is a continuous feedback loop: workout choice informs recovery data, which shapes the next recommendation — and becomes more accurate over time.
"We built Ultrahuman to help people understand their bodies. 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," said Mohit Kumar, CEO, Ultrahuman.
Marina Nola, Chief Digital Distribution Officer at Les Mills, said: "Partnering with Ultrahuman enables us to bring a new level of personalization to fitness. By combining the real‑time insights of the UltraHuman smart ring with the proven motivation of Les Mills workouts, we can guide users towards the right workout for how they feel in the moment and help them stay engaged. Together, we are helping people to build sustainable habits, achieve their goals, and ultimately fall in love with fitness as part of our mission to create a fitter planet."
The Les Mills PowerPlug is available to Ultrahuman Ring AIR and PRO users from 22nd April, rolling out via the Ultrahuman app. It’s available globally, costing $11.99/month or $99.99/year
