How can I become and stay fit?

Move and eat well. Do you think that you are not fit now? If the answer is yes, start slowly. Make small,changes in your diet and begin walking more and taking the,steps,when you can . Focus your attention on long term general fitness,rather,than an immediate fix with a diet or extreme exercise program. Fitness is a,way of life, not one event. As you make these small changes, you may also consider joining a gym.
