It takes more than exercise to be healthy and fit. You can't justify bad habits with exercise. Its like ordering a Henderson's 3 piece with a peppa and drinking a diet coke. You need proper fuel and hydration. THINK WELL OLD MACHINE! Exercise is good for the body BUT our body can see it is stress and if you don't supply your body with what it needs it can backfire on you. Take the time to evaluate your lifestyle and habits and see if it lines up with what you want to accomplish. Be Healthy and Run happy!
