So I just sat in my chair and didn’t move and so I got big. A year ago a doctor worked on me and now I’m not blind. But I was 170lbs and then became 300lbs. I tried a trainer but all he did was yell. And for $600/month it wasn’t worth it. I tried the lose it program and fit bit. It’s good to know everything you’re doing, but it doesn’t interact with you like lark does. In two weeks, I've lost 5lbs. because of it!
