I Need This

Hey everyone, my name is Tyler. I am a teenager living in South-west Florida, I have not been overweight my whole life, but I have recently saw myself gaining a lot of weight. I play Football, but that literally doesn't help at all, plus the season is over. I am currently 228 lbs and I would just like to feel comfortable at the beach when I take off my shirt. I don't even care about having "definition" for now, I just want to feel confident. If anyone is out there that would want to keep me motivated, please do so. Thanks.
