My name is Rachel Flint, and I struggled with this as well.
I wasn't always active. In fact, I was really just going through the motions of my life. I never challenged myself and so I thought I was comfortable....until I wasn't.
About 10 years ago, I was doing what I did. I was flipping channels, eating whatever I wanted at the time and something caught my attention. It was a show about a slightly overweight woman, who was training to become a fitness competitor. She was ready to give up her comfort to do something that would make her feel better about herself.
I started to research and learn everything I could. Eventually, I started a Facebook Group and it grew. Because I simply shared what I was learning and how it was impacting me.
