You have to stay motivated for personal training to be effective. Promise yourself a reward if you reach a certain goal, whether that's a new pair of shoes or an ice cream cone. In addition, make sure you have a support group that can help you through the rough spots.

Evaluate the results of your personal training program realistically. This will keep you grounded, and may serve as a form of motivation. You'll soon realize that although you may not get where you're going as fast as you like, it's obvious that you're on your way.

If you're trying to lose weight with your personal training program, realize that any weight loss is likely to slow as you trim down and gain lean muscle mass. Muscle is significantly heavier than fat, so you may end up weighing about the same even as you're shrinking your waist size.
