Yeh i've told him he needs to do something asap because his knees are going to be fucked soon. He is a good friend and so I don't want to see him completely fuck himself over. I said rowing or swimming would be good, he would probably feel right at home submerged in water ;) whale jokes aside he would be pretty heavy if he was in shape. Being obese is just putting so much strain on his joints and god knows what else
