It may surprise you but Neanderthal girls had bigger biceps than today’s men and globally Neanderthals had a greater muscle mass than us. By analyzing their bones, scientists discovered that Neanderthals had huge biceps and calves. This exceptional strength and muscle mass can be explained by their hard-life as hunters. In fact, Neanderthals were not afraid to hunt huge animals such as mammoths and woolly rhinos. So maybe the key to have a M. Olympia physique is to spend a decade in the woods hunting?
