Functional overreaching and maximizing rest time

Functional overreaching is when you push your body beyond its limits of recovery, requiring extra rest time to recover and improve muscle and strength. By condensing a week's worth of training into half a week, you can achieve functional overreaching. It's important to reduce load and increase reps during this time to ensure safety and avoid injury. The extended rest period allows for recovery and growth, resulting in similar muscle growth as compared to a normal training week. However, it's crucial to avoid overdoing it and only practice functional overreaching for a limited time.
