Some body images to aim for in your training. One size  doesn't  fit all in this game... make sure your goals are realistic!

 Don't just think about what you look like now - and what you are struggling to do in your sports. Think how easy it is to improve on where you are now - that's your achievment and motivation to keep on working on it. Maybe you want endurance and cardio fitness rather than big muscles. Train appropriately. If the opposite - OK again, but get advice. Different aims need different approaches. But celebrate the continuing improvement.  Plenty of examples here!
