Make small, achievable lifestyle changes and stick to them
E.g. drinking 8 glasses of water a day won’t cost you an Öre and will boost your energy levels significantly, because Muscle is 70% water so if you hydrate properly you’ll be able to work harder and get better results. Other changes that are easy to achieve include eating good complex-carbohydrate foods such as grains and vegetables and avoiding/ limiting bingeing on alcoholic drinks as this breaks down muscle.
