Kat is a wife and mother of two active, beautiful daughters. Although, she was fit as a child, she became overweight after marriage and having her two daughters. When her youngest was two, she knew she had to make a change. She wanted to be healthy and live a long life for her family, so she became very active in triathlons, cycling and running races. That’s where the love affair with fitness began. After the age of 40, she found resistance training and she hasn’t looked back. Kat is in the best shape of her life and has found a new passion in helping family and friends really learn what it means to be healthy and fit. She recently became a Cooper Institute-CPT and focuses on helping others be the best they can be by obtaining a new level of confidence and security.
