All starts with how you are eating! Learn how to prep whole foods and make that your new palette. Eating right will make you feel better and motivates you for the gym. I would also recommend just moving your body in general. Start with hour walks and then in the gym keep movements simple!! Dont go crazy with the workouts, btw you totally got this. If you start now you can see progress with in 10 weeks, with discipline ofc!! Good luck
