If you can afford it, Dr. Carter suggested going to a certified personal trainer consistently for a few months. That way, you can get structure and insight into proper form, and you'll be able to take that with you back to your own home workouts. This is especially something she recommended for people new to fitness. "They can keep you up to date on newest techniques and thinking about how to approach physical fitness and putting together a personalized program," she said. Then, once you've got a good foundation, you can go less frequently for check-ins to make sure you're not acquiring any bad habits or improper form. Trusted organisations for certifications are, for example, NASM, ACE, ISSA, and ACSM.
