Too often we wait for the MOTIVATION to exercise, but waiting for that is like waiting for the MOTIVATION to scrub the toilet. I mean, do you really want to clean it? NO..but it's something that has to be done and when you do it, you're really glad you did..so instead of just waiting for that feeling that may never come, why not try to create your own motivation instead?
Give yourself a reward for finishing your workout such as - a new book to read, a night out, or even an extra glass of wine.
Write down your goal and put it in a visible place. Hopefully such a reminder may be enough to get you started (which is always the hardest part).
Please stop waiting and start doing!
