1. Don't worry about calorie counting or fad diets, aim to eat healthy, nutritious and balanced meals. I follow the Paleo eating plan - which isn't a diet! It's just eating the things we're supposed to eat and cutting out the modern, processed, toxin laden, sugary rubbish that is responsible for so many peoples poor level of health and fitness.

3. Rest is important and try not to stress. Sleep is important for so many of our body's processes- neurological performance, hormone function, immune system functioning, and musculoskeletal growth and repair.
