It's very important to set specific, realistic goals. If your goals are vague, and if you don't kick off with a clear idea of where you're heading, chances are that you'll soon hit a wall, or stop your exercise regime prematurely.

Set clear, realistic long-term goals (three to six months from now) to stay focused, but break it down into short-term (weekly) goals to keep motivated. Achieving your weekly goals can work wonders for your adrenalin levels and self-esteem.

This guide will help you to set those long-term and short-term goals.
