Your Ring calculates a Training Readiness Score every morning from sleep, HRV, resting heart rate, temperature, and your current cycle phase. So you know exactly how hard to push today, and when to pull back.
Thousands of workouts, classes, and programs from the world's leading trainers.
Ring AIR available at 15% off, only through this partnership.
Experience the workouts loved by millions, now personalized to you through your biomarkers.
Your Training Readiness Score sets the pace. Your cycle phase shapes the session. Your biomarkers pick the intensity. The Les Mills PowerPlug puts all three together.
Set your weekly training frequency and what you're working toward — building strength, sharpening cardio, losing weight, staying consistent — and the PowerPlug adapts its recommendations to match, session after session.
Your Ring reads your HRV, sleep, resting heart rate, skin temperature, and training load — and turns it all into one score, so you know exactly how hard to push.
Press play on any Les Mills workout. Your Ring logs the full session: heart-rate zones, calories, duration, and recovery impact. Tomorrow's recommendation accounts for today's load.
Your body's capacity shifts across your menstrual cycle. Your training should too. The Les Mills PowerPlug reads your cycle phase from your Ring and matches the session: peak strength and HIIT in the follicular phase, steady cardio and pilates in luteal, restorative work during menstruation.
When your skin temperature runs elevated, the PowerPlug knows you may be fighting something off and drops intensity. When HRV is low, it steers you toward mobility and recovery. When you're green across the board, it unlocks strength and HIIT. Today's workout responds to the data you gave off last night.
Explore a full library of expert-led programs, new releases every quarter, and a workout to match every mood and every minute you have.
What's next for the Les Mills PowerPlug. More ways for your Ring to shape your training.
Structured programs that adjust weekly based on your actual biometric response, not a fixed template.
Fresh releases land every quarter. New programs, new workouts, new music, new instructors. The PowerPlug folds them into your recommendations as they arrive.
