Teresa Briest


While playing youth sports at the age of 12, Teresa was told her knees weren’t built for intense exercise. Swimming was suggested instead of basketball along with physical therapy and adaptive physical education. That one suggestion, although very difficult to grasp, lead to a whole new path for Teresa and athletics. She grew strong in high school and college swimming and developed a love for the sport. While pursuing her education degree, Teresa decided to continue her swimming as a coach at the high school level. Coaching and teaching techniques became second nature for Teresa.

In 2007, a good friend, Darcy Franklin, suggested triathlons. She was hooked after winning her age group in her very first race. But in 2010, Teresa had a season ending foot injury. With determination and the guidance of Darcy, Teresa started her CrossFit training journey and has never looked back. She sees the benefits of high intensity training along with Olympic weight lifting when swimming in masters swim meets. She has never been stronger and holds MN age group records in swimming to prove it! Along with being head coach and owner of Tangletown CrossFit, Teresa is the owner and coach of I Swim Masters Team in Eden Prairie.

Teresa had progressed in her CrossFit training to now include competitions. She has many successes with team competitions and has accomplished a personal goal of finishing the masters qualifier every year since 40 years old. Teresa views CrossFit as an excellent workout for all fitness levels and is an encouraging coach who wants to help others meet their personal goals!

Outside of the gym, Teresa enjoys spending time with her husband and children, eating cheese, cheering on any Badger team, and playing with her dog.
