BLOCK BUSTER #1—Get Started. It sounds simple, but making a commitment to regular exercise is key. Make a list of why you want to exercise and refer to it often.

BLOCK BUSTER #2—Plan to Exercise. By making a commitment, either to your schedule or to another person, you are more likely to keep your appointment. Be specific with times, locations and activities.

BLOCK BUSTER #3—Determine Your Exercise Personality. Exercise has many components—social (high to low), competition (high to low), mood state, location preference and optimum time of day. By determining what's best for you, you will choose the activities that suit you best.   

BLOCK BUSTER #4—Set the Right Goals. Many people focus on outcomes—say, losing 30 pounds—instead of process, such as exercising 30 minutes a day four days a week. The problem with an outcome goal is that if you do not meet it, you'll feel like a failure. If your process goals are realistic, the outcome goals will take care of themselves.

BLOCK BUSTER #5—Hold Mental Rehearsals. By frequently picturing events, you can program your mind, body and emotions to perform the way you want them to. Visualize the activity you want to perform and the outcome you seek.

BLOCK BUSTER #6—Reward Yourself. Rewards are a great way to keep you going. After you have reached a milestone, treat yourself to a massage, a gourmet dinner out, a new CD. In time, the benefits of exercising will become their own reward and the exercise habit will reinforce itself.
