He is 16 next week. He does no exercise. Doesn't do PE at school and all his friends live nearby so doesn't do much walking and school is literally across the road. He is quite overweight (a fair few stone) and whinges about it constantly. He'd like a girlfriend and sulks because he can't get one. Yet he doesn't do anything about it. He has a takeaway every other night if not every night with his mates, they all put money to it and there's loads of them so it's practically free.
Me and DD17 go to the local gym a couple of times a week (not together). I suggested DS joining as well as he'd also get a discount. He scoffed at the idea of going to the same gym as us but said he'd join the one in the next town over which is a short tram ride away, so I said okay. He went a grand total of once in April and I've been paying the monthly fee since, not out of his allowance. He keeps saying "I'll go next week!". Never does, but when I threaten to cancel the membership I get a sob story about how all his mates take the piss and he'll never get a girlfriend and how I can't cancel it. He is a pain in the arse.
I don't really want to cancel the membership as I can see he wants to get fit etc and he doesn't want me to cancel it either, it's just about getting him to go. I've suggested him taking a mate and got an eye roll. DH thinks we should cut off his allowance (30 a month) unless he goes once a week, 4 times a month. The gym he is signed up to is good as you can log in the website and it shows when he's there and how often he's been, so he won't be able to lie to us about going. I'm inclined to agree with DH as it also stops him getting as many takeaway if he doesn't go. I'm sure his mates won't be keen to pay for him/give him bits of theirs after they've all contributed.
