Ultrahuman and Les Mills Launched PowerPlug: Workout Recommendations Driven by Ring Data for $12 a Month

What it is

The Ultrahuman Les Mills PowerPlug is a subscription feature launched April 22, 2026 that integrates Les Mills' studio-quality workout catalog directly into the Ultrahuman app. PowerPlug uses continuous biomarker data from the Ultrahuman Ring (AIR or PRO), sleep, heart rate variability, resting heart rate, body temperature, menstrual cycle phase, to recommend specific Les Mills workouts tailored to the user's current recovery state. A well-recovered user sees high-intensity options like BODYPUMP or BODYCOMBAT surfaced first; a user with sleep debt gets routed toward BODYBALANCE, yoga, or mobility sessions.

Pricing: $11.99/month or $99.99/year. Requires an Ultrahuman Ring AIR ($349) or PRO ($429) as the underlying hardware.

What's interesting

Dynamic workout prescription is the genuine innovation. Most fitness apps deliver the same workout regardless of the user's recovery state; PowerPlug adjusts intensity based on real-time biomarker data. Android Central called this out as genuinely useful for users who train inconsistently due to travel, work stress, or sleep disruptions.

Les Mills is the global studio-fitness catalog (BODYPUMP, BODYCOMBAT, GRIT, BODYBALANCE, Yoga) with 20+ years of commercial gym deployment. Ultrahuman licensing this catalog for at-home use brings gym-grade workout content to smart-ring users. Athletech News framed this as a credible gym-to-home expansion for Les Mills.

Cycle-phase integration is the differentiator for women. Android Authority confirmed that PowerPlug unlocks high-intensity workouts during follicular and ovulation phases (when performance typically peaks) and routes users toward recovery-friendly content during luteal and menstrual phases. This kind of menstrual-aware training guidance is rare in mainstream fitness apps.

Recovery scoring via Ultrahuman's Dynamic Recovery system incorporates non-sleep deep rest (breathwork, naps), meaning users who actively recover between workouts see that reflected in the next day's recommendations. This feedback loop rewards rest behaviors most fitness apps ignore.

At $11.99/month, the subscription is competitive with Apple Fitness+ ($9.99), Peloton App One ($12.99), and Les Mills On Demand ($19.99). Ultrahuman PowerPlug is unique in the auto-personalization layer.

What's missing or unverified

Requires an Ultrahuman Ring. The hardware prerequisite at $349-$429 is a significant upfront cost. Oura Ring users, Apple Watch users, and Garmin users cannot access PowerPlug without switching rings. For existing Ultrahuman owners the feature is an obvious addition; for new buyers the total cost of entry is $360+.

Les Mills catalog is extensive but not infinite. After 3-4 months of daily use, repeat workouts are unavoidable. Most users pair PowerPlug with other fitness content to maintain variety.

Recommendations are good-but-not-perfect. Android Central's review noted that the recommendation engine occasionally over-indexes on conservative recovery guidance, which can be frustrating for users feeling fine who are pushed toward yoga when they want high-intensity. Manual override is possible.

No Apple HealthKit integration yet for the PowerPlug feature specifically. Ultrahuman Ring data syncs to HealthKit generally, but workout recommendations don't push back into Apple Fitness.

Live Les Mills instructors are not included. All workouts are pre-recorded. For users who prefer live instruction, Peloton or in-person studio classes are the right match.

Who it's for

Existing Ultrahuman Ring AIR or PRO owners looking to add structured workout content. Intermediate fitness enthusiasts who train 3-5 times per week and want data-driven programming. Women who want cycle-aware workout prescription.

Not for: Oura/Apple Watch/Garmin users (requires Ultrahuman Ring), beginners who need instructor feedback, or budget users unwilling to pay $12/month on top of hardware cost.

Verdict

Ultrahuman Les Mills PowerPlug is a thoughtful subscription that genuinely extends the value of the Ultrahuman Ring. Dynamic workout prescription based on recovery biomarkers is rare in fitness apps and Les Mills's catalog is credible at-home content. Against Apple Fitness+ and Peloton App, PowerPlug wins on biomarker-driven personalization; it loses on exercise variety and live instruction. For Ultrahuman owners, this is a reasonable add-on.
