When trainees return to a training session after lunch feeling tired, this phenomenon is referred to as the "post-lunch dip," according to Peter Quarry. It is a common occurrence where individuals experience a decrease in alertness and energy levels, often impacting their ability to engage effectively in the session. This can be attributed to various factors, including the body's natural circadian rhythms and the effects of digestion. Strategies such as incorporating interactive activities or energizing breaks can help mitigate this dip.
