As a health coach, I have become curious about the amount of people forcing themselves to undergo strenuous exercise in the name of weight loss or good health. I have a secret for you that might blow your mind a little. For the majority of people, strenuous exercise, if done out of force or in a state of stress, is not actually good for your health or a good way to burn calories and increase yourthermic efficiency (metabolism). If we hate every minute of our work out, our body is going into a physiologic stress response. Under stress digestive capacity is diminished, metabolism slows down and digestion can even shut down in extreme cases! We don't assimilate nutrients well, and we don't feel well.
