1. Episodic memory is also known as long-term memory, and the researchers approached the study of exercise in a different manner than previous studies. Other studies examined the impact of aerobic exercise conducted over many months, but this study simply asked participants to lift weights a single time. During the test, half of the participants were asked to use a weight machine before recalling a series of images they were shown at the start of the test. The other half of the participants were also asked to recall the images but without having engaged in any strenuous activity before the recall session. In demonstrating the memory improvement for the participants who engaged in just a single session of weight lifting, the researchers were able to show that improving one's memory through exercise didn't take hours of dedication in the gym. The next time you have the opportunity to lift weights or someone tries to convince you to join the gym you might just want to take him or her up on the offer.
