While your early enthusiasm might make you feel like you want to get into your training in a big way from day one, make sure that go with what your plan tells you. Doing too much too soon is likely to lead to injury.
Believe in yourself and don’t give up. There will be plenty of times when you doubt your ability to follow your plan and achieve your goals. Don’t lose sight of your goal and keep at it. We all have bad days but don’t let them affect your overall programme.
