It has become popular in health and fitness circles to say that age is just a number, that you don’t have to get old, but we know that is not true. But while everyone is getting older, some are clearly doing a better job of it than others, and in doing so, changing what it means to get “older”. And contrary to popular belief, research has shown that 70-80% of the difference in how people age comes not from the “luck” of good genetics, but rather the actions that people take, more a matter of “nurture than nature”. Age is a critical factor in fitness training, and has to be taken into account. It is pretty clear that the older you get, the smarter you need to train. And athletIQ is here to help you train smarter.
