Achieving your goals or desires for health and fitness often requires changing your thinking, and one of the best aids is keeping a journal of your daily nutrition, physical fitness, and accompanying thoughts. Your physical person is more than just what you eat; it’s also the result of what you choose to put into your workouts. And it’s heavily influenced by how you feel, which is directly related to what you think about yourself. They all must work together if you want to be healthy and fit.
