If you want to lose weight, get healthy and/or build muscle, hiring a personal trainer can be a step in the right direction. A good trainer can help you set up a program that meets your goals and teaches you the best way to exercise. Here's what you should know before you decide to hire a trainer.

What is a Personal Trainer?

A personal trainer should be, at the least, educated and certified through a reputable fitness organization (see below). This person's job is to assess your fitness level, set up a program for you and keep you motivated. He or she will push you past your comfort level--something difficult to do on your own. A trainer also provides:

• guidance on reaching your goals
• education about strength training, cardio and basic nutrition
• a reason to show up at the gym each week
• accountability
• ways to help track your progress

What is a Session Like?

Each session lasts about an hour. The first meeting is devoted to assessing fitness level, body measurements, exercise and health history and goals. Be prepared to step on the scale, have your body fat tested and answer specific questions about your goals. After that, you'll spend most of your time on strength training and cardio.

What to Look for In a Personal Trainer

• Education: A personal trainer should be certified through a reputable fitness organization. An exercise science or other related college degree isn't necessary, but the more education your trainer has, the better your workouts will be.
• CPR: your trainer should have an updated certification in CPR and/or first aid.
• Experience: Make sure your trainer has several years of experience, especially in relation to your goals. For example, if you're a bodybuilder, you want someone knowledgeable in that area.
• Specifics: If you have a specific medical problem, injury or condition (such as being pregnant, heart problems, diabetes, etc.) make sure your trainer has education in these areas and will work with your doctor.
• A good listener: A good trainer will listen closely to what you say and make sure he understands your goals.
• Attention: A good trainer will be focused only on you during your sessions.
• Tracking progress: A good trainer will regularly assess your progress and change things if necessary.

Personality is important too since you'll be working very closely with this person. Make sure you get along with your trainer and feel comfortable asking questions.
