The Science of Rest Days
Rest days are not just breaks from training – they’re when your body repairs, rebuilds, and becomes stronger. Understanding the physiological benefits of recovery helps maximize your fitness results.
Why Your Body Needs Recovery Time
- Muscle tissue repairs and grows during rest periods
- Energy stores (glycogen) replenish
- Central nervous system recovers from stress
- Hormone levels rebalance
Signs You Need a Rest Day
- Persistent muscle soreness lasting more than 72 hours
- Decreased performance in workouts
- Elevated resting heart rate
- Irritability or lack of motivation
