Many people are interested in hiring a personal trainer to help enhance their workout routine. However, there are a few things you should look for prior to giving someone the thumbs up to manage your exercise plan.

The Centers for Disease Control and Prevention says that ages 16-64 can benefit from at least one hour and 30 minutes of intense physical activity per week. However, it can be difficult to motivate yourself to get off the couch, which is where a personal trainer comes in handy. Consider these factors when going through the hiring process.

1. Past experience. Because your personal trainer is technically applying for a job, the American Council on Exercise recommends inquiring about the individual's past experience. Don't shy away from asking what type of clients the trainer has worked with and any areas of specialization. If you are looking for a professional for rehabilitation purposes, make sure they are willing to work within your medical guidelines.

2. References. Looking over an applicant's references is one of the best ways to gain more insight into past experience. Don't be afraid to ask for testimonials and phone numbers of clients. It doesn't hurt to get a second opinion.

3. Education. It is in your best interest to look for a personal trainer with a degree in exercise or physiology. This can provide you with the extra reassurance you need to invest your trust in the professional. If possible, consider applicants who have an accredited certification, such as ACE or NASM.

4. Policies. Remember, you're essentially hiring an employee. For this reason, it may be best to ask for descriptive details on the trainer's policies. Inquire about cancellation fees and preferred methods of payment.

5. Connections. It also helps to determine whether candidates you are interviewing have connections to other professionals in the industry. Personal trainers who are regularly in contact with medical experts and others in the field are more likely to be up-to-date on industry trends. In turn, this can ensure you're getting the most bang for your buck.
