Zenshin – Strength & Recovery

Zenshin is strength training built for the next forty years, not just the next twelve weeks. Most lifting apps simply record what you did. Zenshin helps you understand how recovery, strength training, running, cycling, and other activity fit together, without accounts, advertising, or tracking. RECOVERY-AWARE TRAINING With your permission, Zenshin reads recovery signals from Apple Health, including heart rate variability, resting heart rate, and sleep. It calculates a clear daily readiness score on your device. Your readiness score is free. Zenshin Lifetime adds deeper recovery interpretation and can adjust a planned session when your recovery calls for a lighter day. You can always see what influenced the recommendation and choose whether to follow it. COUNTS YOUR WHOLE TRAINING LOAD Zenshin considers runs, rides, walks, and hikes alongside your strength training. Zenshin Lifetime turns that activity into combined training-load trends, helping you notice when overall strain is climbing. KNOWS WHEN TO BACK OFF When fatigue patterns build, Zenshin Lifetime can suggest a lighter week before they derail your training. Taking a well-timed step back is part of making sustainable progress. SUSTAINABLE BY DESIGN Choose a training intent focused on longevity, hypertrophy, or strength.
