- Why the same physical effort feels harder during different weeks
- Mapping hormone shifts to energy states
- Higher pain tolerance occurs when estrogen is rising
- Muscle recovery is faster during the first half of the cycle
- The ovulatory phase is the peak of physical strength
- The late luteal phase is the lowest point for high-intensity work
- Recognizing signs of a high-intensity phase
- Predicting energy peaks across the cycle
- The body is more sensitive to stress in the second half of the cycle
- High-estrogen days are best for hitting personal records in the gym
