Lean Muscle Club

Build strength. Keep it simple. Lean Muscle Club brings guided workouts and everyday habits together. Available in Simplified Chinese and English. MOVE WITH A PLAN Choose from 14 built-in routines for home, gym, and mobility. Follow exercise cues, mark each set, and use rest timers to keep your session moving. SEE THE MOVEMENT Watch animated exercise demonstrations. Pause a demo, slow it down, or view a representative pose. With Reduce Motion enabled, demonstrations use a still pose. Animation speed does not set your workout pace. KEEP DAILY HABITS VISIBLE Log your water intake and sleep duration. Review today's check-ins alongside your training activity. FOLLOW YOUR OWN PROGRESS Record weight and waist measurements and review your recent activity. Focus on your own consistency rather than comparing bodies. OPTIONAL APPLE HEALTH With your permission, view sleep, weight, and waist measurements from Apple Health alongside your manual records. Access is read-only. The app does not write or upload these HealthKit samples. CHECK IN AT A GLANCE Choose to show whether today's workout, water, and sleep have been logged on widgets and a paired Apple Watch. This optional sharing is off by default. It excludes detailed measurements, HealthKit samples, and account information. LOCAL-FIRST TRACKING Core logging and training work without an account. Training and body records are stored on your device. You can export your records when you choose. Whether system backups include app data depends on iOS and your device settings. Exercise content provides general fitness information, not medical advice or an individualized training prescription. Choose movements and intensity that suit your circumstances. Stop if you experience pain or feel unwell.
