The aim of the recovery period between sets is to replenish the stores of ATP and Creatine Phosphate (CP) in the muscles. An inadequate recovery means more reliance on the Lactic Acid (LA) energy pathway in the next set. Several factors influence the recovery period, including:
- Type of strength you are developing
- The load used in the exercise
- Number of muscle groups used in the exercise
- Your condition
- Your weight
A recovery of three to five minutes or longer will allow almost the complete restoration of ATP/CP.
