Rest between sets

The most important factors for hypertrophy and strength adaptations are:

1. Volume
2. Training to near fatigue
3. Intensity (with intensity being more important than training to fatigue if strength is the primary goal)

Rest times between sets do not seem to impact hypertrophy or strength so long as these other factors are met. In fact, there is data suggesting that strength and performance are impaired if not enough rest is taken between sets. As such, we recommend resting as long as is required to feel physically and mentally fresh for the following set and ready to give it your complete 100% focus. If time constraints are an issue then you can take shorter rests with the understanding that performance may suffer to a certain extent.
