Conventional wisdom says the best way to build your fitness is to lace up your runners,  find your ‘Cardio Zone’  and stay there for 45-60 min several times per week.

But increasing evidence is piling up suggesting this is – in fact – not the best way to get lean, strong and fit and can actually be downright dangerous.

In this post I want to get specific and look at some key by-products of chronic cardio and how that may be holding you back from reaching your health and fitness goals.
