Try to get somebody to exercise along with you. But it should be somebody committed or else your interest might dwindle. This is indeed an excellent idea. One of the advantages of getting a committed person t exercise with you is that it keeps you going.
There may be days when you feel just too lazy to crawl out of bed in the mornings. On such days, the knowledge that some body is waiting for you is enough to slide out of bed.Another advantage is that you can discuss your progress and fears with another person and be a sympathetic listener to the other person as well. This is a fine way of getting motivated your self.
