It is very likely that you are devoting a significant amount of time these days to memorizing law in anticipation of the July bar exam. If you are struggling to retain this knowledge, you might want to try exercising four hours after studying.
Why four hours? Well, a study published in the journal Current Biology found that physical exercise after learning improves memory and memory traces, but only if you exercise four hours after learning. The scientists discovered that those who exercised four hours after their learning session retained the information better two days later than those who exercised either immediately or not at all. It is still unclear why the delayed exercise has such an effect on memory.
If you are struggling to memorize the elements of crimes or torts, you might want to go for a run or hit the gym four hours after studying. It couldn't hurt to try.
