False – over-training can actually be really unhelpful to your goals and life in general! Everyone needs a rest day or two to give your muscles and energy levels time to repair and grow.* Anyway, life is about balance. Go and meet your friends, catch up with your family or just spend the evening relaxing and you’ll be much more keen to get back in the gym tomorrow!
*If you really don’t want to have a rest day then mix up your training and do yoga or pilates instead of hitting the gym.
