<human>:  I'm thinking of becoming a personal trainer, what qualifications do I need?
<bot>: In order to become a personal trainer, you will need to have some kind of certification in the field, such as a nationally recognized personal training certification. You will also likely need to have CPR and First Aid certification, and knowledge in exercise physiology and nutrition. Depending on the state, some may also require you to have a degree in a related field. Additionally, having a liability insurance policy is highly recommended.
