Founder of TogetherWON and senior fitness specialist
Kristen Nielsen is the founder of TogetherWON and writes its weekly letter and guides for adults over 60. She’s an ACE Certified Personal Trainer and Senior Fitness Specialist with more than 10 years in functional aging, a University of Central Florida graduate, and a former Division I swimmer and track and field athlete.
Founded TogetherWON in 2016
Kristen has been an athlete all her life, and she competed in swimming and track and field at the Division I level. Her grandparents' vitality later in life, and seeing what strength training could do for older adults, led her to make fitness after 60 her work.
Her very first client, in 2016, was her own mom, Julie. Julie later came back strong after a hip replacement, and at 75 she calls her replaced hip one of her better joints. Read Julie's story.
Kristen built TogetherWON around one approach for the body, brain and balance. Today our trainers work with adults over 60 in their homes in Colorado Springs, Monument and the Tri-Lakes area, and online through the TogetherWON app, which her husband, Aaron, built.
Every Saturday, Kristen writes a letter with one idea for your body, brain or balance, usually with a recipe. She has turned the best of them into guides on topics like strength training, balance, brain health and nutrition after 60.
