I've always been into health and fitness, but really struggled with the "all or nothing" and "more is better" mindset, which messed up my hormones and really ruined my relationship with food and exercise for a very long time.

Luckily for me, getting pregnant with my twin boys (via IFV after years of infertility issues) was the point at which I finally started to listen to my body. I learned how to balance my hormones through diet and exercise and in doing so I got better results than I ever did following restrictive diets and exercising hours and hours a week.

My mission is to help as many women as I possibly can develop their own version of "The LEAN Life", which is my acronym for a Lifestyle of Efficient exercise and Automated Nutrition. As a working mom, I don’t have the time or the desire to stress over food and exercise but I DO want to feel great in my clothes, have the energy to keep up with my VERY active boys, continue to repair my relationship with food and take care of my hormonal health which is super important to me now that I'm in my 40s.
