Rest intervals

Topic

Rest intervals are the designated periods of inactivity or low-intensity recovery between sets of exercises or high-intensity training bouts. They are a critical variable in exercise physiology and resistance training, directly influencing fatigue, metabolic recovery, and long-term adaptations such as muscular strength, hypertrophy, and endurance. The duration of these intervals is typically tailored to specific training goals, ranging from short periods for endurance to longer durations for maximal strength development.
