If you think of personal trainers as a luxury only pampered celebrities get to enjoy -- think again. Hiring a trainer isn't as pricey as you might think. You could spend more on a pair of shoes than you would for several sessions with a fitness pro.

So, what are some of the benefits of using a trainer? He can fine-tune your workouts so you'll get results without wasting a lot of time or energy. He can ensure that a routine is safe, effective and tailored to fit you and your needs. And most important, he will help you set realistic goals and keep you motivated.

Trainers charge a wide range of fees for their services. Typically, they can cost anywhere from $20 to $100 per hour. But there are a few ways to minimize the fee: Round up a couple of friends to work out with and split the cost (many trainers allow group sessions). Or you can also spring for a few sessions to get you started with a new routine. Then, you can just treat yourself to periodic check-ins to make sure you're still on the right track. You shouldn't commit to a number of prepaid sessions with a trainer until after you've worked with him for a while and know that you connect with him. Instead, pay as you go.

What should you look for in a trainer? First, he should hold a current certification in CPR and be certified by an organization such as the ACSM (American College of Sports Medicine) or ACE (American Council on Exercise). You can search online for certified trainers near you here or by visiting the ACE's website. Next, make sure your schedules are compatible. If he's not available on the days and times when you want to work out, find another trainer.

Also, it's important that you feel comfortable with your trainer; this encompasses many things, including personality, gender and coaching style, as well as personal habits and behaviors. He should also have a solid understanding of exercise, physiology, safety, equipment and nutrition. And finally, he should motivate you. If you aren't being pushed to achieve your goals, you're wasting your time and money.

Feel free to set up appointments with several candidates to find the right one for you. Ideally, you're looking for someone who listens and communicates well. He or she should ask you about yourself, your lifestyle and your goals. He should promote an integrated program that includes strength training, weight management, cardiovascular exercise, nutrition and flexibility training.

Then, enjoy the star treatment as your trainer offers you personal attention, professional advice and all the encouragement you need.
