Hi, I am Carmen a crazy workout enthusiast that loves going to the gym. It wasn't always so but it took time and effort to build up the habits and commitment to stay fit and stay committed. I hope my writing will help encourage you on your journey. I am the perfect example of somebody who walked into a gym and was completely intimidated. I was not a high school athlete. I danced growing up, mostly ballet. From there I found yoga, spin class, and whatever else the local gym had to offer that promised great results. I love sharing and writing about what I learned from others, as well as from my experience. Hope I will have your ears.
