Prepare meals and workouts ahead of time to stay on track with your fitness and nutrition goals. Eat 5 small meals per day instead of 3 large ones to boost your metabolism and prevent overeating. When eating, use portion control and choose foods with nutritional value. When exercising, pay attention to your form and range of motion to get the most out of your workouts while avoiding injury. Change up your routine periodically and listen to your body's needs.
