I was searching for a story on the old form that's at least 2 parts in which there were two teenaged brothers. One of them was suddenly growing very quickly, but only in response to workouts (although there were hints that this was going to change soon). And the school gym was already insufficient for any further needs. So the two of them broke into a fitness supply store one night and were stealing equipment they couldn't otherwise afford, plus a lot of supplements. The one who was growing got bigger just thinking about what he was going to do with all this stuff. Any help tracking these down would be appreciated, thanks!
