My Name is Jimmy G

My name is Jimmy G. I had lost 55 lbs but over the last 3 months have gained back 20. I CANNOT let myself get back up to 240. My weight has yoyo'd my entire life. My goal is to get to 170 and stay there. I am currently at 205. One would think that after 2 heart attacks taking care of oneself would be a priority! In the winter I am about as active as a slug. I really need to get my butt of the couch. Wish me luck!
Thanks
