Caitlin Harrington ACSM-CES, ACSM CPT, CES, PN-1

I am the founder of Next Summit Fitness and a graduate of the University at Buffalo with a Bachelor’s degree in Exercise Science. I have over 15 years of experience helping clients move, feel, and live better. I hold certifications through the American College of Sports Medicine (ACSM) as both a Clinical Exercise Physiologist and a Certified Personal Trainer. In addition, I specialize in pre- and postnatal corrective exercise and hold a nutrition certification through Precision Nutrition.
Throughout my career, I’ve worked with individuals across all stages of life—from those seeking general fitness to clients recovering from injury or managing chronic conditions. My passion lies in empowering women to maintain or rebuild their strength, restore core function, and feel confident in their bodies as they move through life’s many transitions. Whether you’re returning to movement after childbirth or simply looking to feel stronger in your day-to-day activities, I’m here to support your journey with expert guidance and care.
I currently reside in Ballston Spa with my husband, two children and dog. You can often find us playing sports in the backyard, enjoying nature and the local lakes, shuffling between kids sports and activities and spending time with family and friends.
