There are a variety of reasons why the 'before' picture of this woman looks the way it does. She'd had two children, and gained weight during both pregnancies. The second pregnancy was difficult, and her child had medical problems at an early age, which took up all the free time she had. She was also self-employed, and had to devote a lot of time to her business. In short, she didn't feel like she had any time to go to the gym and work out. Then she found a solution.
There's no need to go to a gym if you can set up an equivalent in your own home - and she had a garage going spare. It was much easier to go in there and work out than it was to find the time to go to and from the gym, so she committed to doing that every day. Now 65 pounds lighter, she no longer has her old business - because she's started a new life as a personal trainer and fitness coach.
