Muscle Is Built During Sleep

During deep non-REM sleep, human growth hormone (HGH) surges and protein synthesis reaches peak velocity. Failing to monitor recovery readiness often leads to overreaching and chronic cortisol elevation.

How Beyounge Computes Your Readiness Score

By integrating with Android Health Connect, Google Fit, and wearable sensors, Beyounge synthesizes Heart Rate Variability (HRV), resting pulse, sleep phase distribution, and muscle soreness logs to generate a daily 0-100 Readiness Score.

On high readiness days, Beyounge prompts you to tackle heavy compound movements. On low readiness days, the AI seamlessly transforms your workout into active mobility and active recovery cardio.
