Fitness trainers instruct others on how to exercise properly and assist them as they learn to live an overall healthy lifestyle. A trainer can help a client one-on-one by putting together a workout plan for them and demonstrating the right way to perform the movements. Their advice can help patrons get the results they want from working out while also preventing injuries.
A trainer can also teach group fitness classes. Depending on their experience and certifications, a person might lead a session of aerobics, yoga, high-intensity interval training, or a similar activity with a room full of people. Through these sessions, trainers provide fun, shared opportunities for others to move their bodies.
