Research from Denmark has shown that leg size can make all the difference in heart health. Scientists followed almost 3,000 men and women for more than 10 years for development of heart disease and total death. Those with a leg size just below 22 inches (measured at the top of the leg) had about double the risk of developing cardiovascular and coronary heart diseases, as well as total mortality, over those 10-plus years. Bodyfat had no influence on the association of larger leg size and reduced risk of cardiovascular diseases and total mortality. The team concluded that having greater muscle mass appears to provide protection from developing cardiovascular disease and overall risk of death. So get to work on those legs. We’re not suggesting you bring them up to Kai Greene’s level, but just make sure they’re larger than 22 inches in diameter.
