The advantages of this format are that the body will be given sufficient time to adapt to the training stimulus without being overloaded. There is sufficient relative load from week to week to ensure progress is still being made. I want to highlight that just because a lift is relatively easy, does not mean that it is not producing great stimulus for improvement. As we training at higher intensities, so increases the risk of injury. Would you rather be patient with your progress or have to take 4 weeks out to recover from an injury every few months?
