A personal trainer is someone who helps people exercise. Trainers usually need to be certified before beginning to work in a club or facility in the U.S. You should consider getting a personal trainer if you are in any of the following conditions:

1. You're totally out of shape. The range of exercise equipment and techniques available can be daunting if you have been a couch potato for a long time. A personal trainer can guide you on your best options. Do you do a cardio first or weight training? Should you use the stationary bike or the treadmill? A trainer can help you into the right exercise program that matches your current fitness level. Five to ten sessions with a trainer is usually enough to get you up and running.

2. You're coming back from an illness or injury. If you have a health condition, a previous surgery, or an accident, a trainer can help you recover faster. Be sure to check first with your doctor and screen carefully the trainer as you can easily make things worse with a wrong rehabilitation program.

3. You want to review your program. If you feel your current regimen is not working for you, a trainer can assess what's wrong or lacking and advise you accordingly. For example, if you have difficulty meeting your weight loss targets, a qualified trainer can advise adjustments on your cardio exercises, strength training, and even dietary habits.

4. You need a sports-specific training. A personal trainer can help you prepare for your sport or hobby. If you're planning to join your first 5K run or marathon, it pays to seek an expert trainer so he can you help you finish it safely.

5. You need extra motivation. A trainer enables you to stick to your routines. He can give you positive feedback and provide the push you need to keep going. Besides, knowing that you have paid for something is sometimes all the motivation you need to show up at the gym.
