    After many years of inconsistent workouts and fad diets, I decided to become a personal trainer so that I could learn how to help myself and others achieve health and fitness goals by creating lifestyle changes that lead to long-lasting results. My goal is to motivate, inspire and educate my clients about all of the benefits of exercising and living a healthy lifestyle.

    • NASM Certified Personal Trainer

    My name is Nick Anderson. I am an NASM Certified Personal Trainer. I grew up in Warwick, Rhode Island, and moved to East Bridgewater in 2020. I graduated from Johnson & Wales in 2015 with a degree in Engineering Design. I worked for 6 years in the engineering field, and ultimately came to the conclusion that it was not for me. After finding a passion for not only my own fitness, but helping others with it as well, I decided to pursue a career as a personal trainer. I eased into the transition away from engineering in 2020, starting as a part-time trainer, and then slowly moving on to working full time as a trainer. Over the last few years I’ve worked at commercial gyms and training studios across the area, before finally landing at Fitness Together in 2022. I’ve also recently discovered a passion for competitive powerlifting. My goal during my training sessions is to leave you feeling like you were at least 1% better than you were when you walked in the door.

  • I have been working out at FT for a couple of years and it has made a dramatic difference in my health. I no longer need hip surgery and I am able to dance and hike again.

  • The high quality training and nutrition advice at Fitness Together has helped me reach my fitness goals. I’ve lost 20 pounds and have a BMI of 22.8!

  • I started working out after having breast cancer and heading to osteoporosis. My primary goal with FT was to increase bone density. I now have normal bone density.

  • Friendly people who care about helping you achieve your goals. FT helped me prepare to hike the Appalachian Trail at age 65. If you have the will, FT will show you the way.
