If you’re a workout-savvy individual, working with a trainer can improve your performance and help you reach your goals. But it’s not a magic cure-all for all that ails you: A good trainer can make your fitness routine safer and more fun, but ultimately the effort and sweat you put into your training is what will get you the results you want.

A personal training demonstrates fitness routines and techniques to their clients, helps them exercise safely, and provides feedback on their progress. They may also provide nutritional advice, lead group fitness classes, and educate their clients about exercise and gym safety.

Many personal training programs include internship options, giving the graduate some experience before they officially qualify to work in the field. While this might feel like paying for the privilege of having a job, it’s a great way to gain hands-on experience while learning your trade. Most personal trainers also need to obtain property and professional liability insurance.

If you’re interested in becoming a personal trainer, it’s important to research the different national certifications and find one that best fits your skill set and goals. Those who hold a national certification that’s accredited by the NCCA, DEAC, or ACE will generally be seen as more trustworthy and experienced by their peers. Coursework in kinesiology, motor development, anatomy, and physiology is necessary to develop the core knowledge needed to assess and plan effective fitness programs. A strong understanding of psychology is also helpful for motivating clients.
