A study of nearly half a million people has revealed that muscular strength, measured by handgrip, is an indication of how healthy our brains are. So if you are on of those people who thinks that working out is overrated, then think again!

Using data from the 475,397 participants from all around the U.K, the new study (University of Manchester) showed that on average, stronger people performed better across every test of brain functioning used. Tests included reaction speed, logical problem solving, and multiple different tests of memory. The study shows the relationships were consistently strong in both people aged under 55 and those aged over 55.

This takes getting those summer bodies ready to a whole new level!
