Lose fat without losing muscle. Your AI coach tracks your training, body composition, sleep, and recovery to keep you in a sustainable deficit that actually works long-term.
Withings tracks your lean mass and fat mass separately. The AI monitors both over time so you can see whether you're losing fat, muscle, or both. Scale weight alone is misleading - body composition is what matters.
Workout data from Strava and Hevy plus daily strain from WHOOP or Apple Health give the AI a picture of your energy expenditure. It uses this to guide sustainable deficit targets rather than extreme cuts.
When your HRV drops or sleep quality declines, the AI dials back workout intensity. Training hard on poor recovery during a caloric deficit is a recipe for muscle loss and cortisol spikes.
Weekly summaries show weight trends, body fat changes, training volume, and recovery scores. You see the full picture beyond day-to-day fluctuations that don't mean anything.
It combines exercise data, body composition tracking, sleep quality, and recovery metrics to create a training plan that keeps you in a sustainable deficit. It adjusts intensity based on your energy levels and flags when overtraining could stall fat loss by elevating cortisol.
Most users see measurable progress within 2-4 weeks once the AI has calibrated your plan. It uses 7-day rolling averages for weight to filter out water fluctuations and show real fat loss trends.
Yes. Preserving lean mass is a priority. The AI monitors body composition via Withings and adjusts training to include enough resistance work. If lean mass starts declining, it modifies your plan to add more strength training and flags potential nutritional gaps.
Yes. The AI structures a hybrid plan using running for cardiovascular fitness and caloric expenditure alongside strength sessions to preserve muscle. It manages total load so neither suffers.
Workout calories from Strava and Hevy, body weight and composition from Withings, sleep duration and quality from Oura or WHOOP, and daily activity levels. Together these give a complete energy balance picture.
