Should I Rest Today Calculator
Use your sleep, soreness, and resting heart rate data to decide definitively whether today is a rest or training day.
Frequently Asked Questions — Should I Rest Today Calculator
How does resting heart rate relate to recovery?+
Resting heart rate (RHR) correlation: An RHR elevation of 5+ bpm above your personal baseline is a reliable indicator of physiological stress (illness, overtraining, poor sleep). Professional athletes and HRV devices use this metric daily. If your RHR is elevated, your autonomic nervous system has not recovered sufficiently for high-intensity training.
How many rest days per week should I take?+
Evidence-based recommendations: Beginners (0-1 year training): 2-3 rest days per week. Intermediate (1-3 years): 1-2 rest days per week. Advanced athletes: 1 full rest day mandatory with 1-2 deload days. Active recovery days (light cardio, yoga, walking) count differently — they are not full rest days but aid recovery.
What should I do on a rest day to speed up recovery?+
Optimal rest day activities: Light walking (20-30 min) — increases blood flow without muscle breakdown. Foam rolling and stretching — improves myofascial mobility. 10-15 minute cold water immersion (10-15°C) — reduces inflammation markers. Prioritize 8+ hours of sleep — 90% of Growth Hormone is released during NREM sleep. Nutrition: maintain protein intake even on rest days.
Is overtraining syndrome real, and what are the symptoms?+
Overtraining Syndrome (OTS) is a real medical condition defined as performance decline despite adequate rest. Symptoms: persistent fatigue not resolved by 1 week of rest, 5%+ strength or performance decline, mood disturbances (irritability, apathy), frequent illness (suppressed immunity), elevated resting HR 7+ days, sleep disruption, and loss of motivation. Recovery takes weeks to months.
