The proof is in the smiles after the sweat! Believe it! Exercise puts you in a better mood. But before you think that tiny dumb bells or casual walks can give you happiness, be aware that you have to SWEAT with heavier weight training or anaerobic exertion to get the real benefit. Your endorphin level is unique and it will be through trial and error to find the right kind of physical activity that will induce your very own brain “opiates” and get you hooked on feeling the “rush” after sweating it out.
