A Recovery Score is a number from 0 to 100 that estimates how ready your body is to train today. It combines several signals: sleep quality, resting heart rate, heart-rate variability (HRV) and how you feel. The higher the number, the more ready you are for hard training; a low number is a sign to back off.
In HARTLAB this score is calculated automatically from your wellness log so you can train hard without burning out.
Muscle does not grow during training — it grows after, during recovery. The workout only creates the stimulus (micro-damage plus a signal to adapt). Train hard without enough recovery and progress stalls while injury and burnout risk climb.
That is why elite athletes track readiness as carefully as the training itself.
Sleep is the foundation of recovery. Growth hormone is released and tissue is repaired during deep sleep. Both duration (7–9 hours) and consistency matter — going to bed and waking at roughly the same time.
A morning resting heart rate elevated above your baseline is a common marker of under-recovery, stress or an oncoming illness. If RHR is 5–10 beats above normal, dial the intensity down.
HRV reflects nervous-system balance. Higher HRV usually means better readiness; a sharp drop suggests your body is still under stress.
Subjective feel — muscle soreness, energy, mood, motivation — is an underrated but powerful signal. Your body often "knows" before the numbers do.
A Recovery Score works best paired with a Training Readiness Score, which also accounts for your recent training load.
The simplest strategy is autoregulation: keep the same plan, but adjust intensity to readiness.
This is not "skipping" a workout — it is smart resource management. Over a few weeks you accumulate more quality volume than by grinding every single day.
We cover how to add load over time in our guide to progressive overload.
You can, but lower the intensity. One low-readiness day is no reason to panic; the problem is when the number stays low for several days in a row.
The biggest lever is sleep. Then: hydration, enough protein, stress management and light activity on rest days.
No. Even a simple daily rating of sleep and how you feel gives a useful trend. Wearables add precision (HRV, RHR) but are not required to start.
