My son recently graduated from high school. I coached him in baseball from rec to travel to his summer college showcase teams. Around his freshman year my daughter started playing fastpitch softball so I coached and instructed her and soon went from rec to travel. All this means that I spend a large amount of time away from home in ball parks... week nights at practice and maybe a scrimmage, weekends at tournaments sometimes out of town. In theory I can prepare food and take it with me but with team equipment, etc. it is tough to do. Time between games is spent watching other teams, getting a bit to eat and figuring out what to do for the next games. After the day is done the team gets a bite to eat together (usually) and back to the hotel.
All this points to weight gain during the summer. Should it? Of course not if I wasn't an idiot but over the years it has greatly contributed to "the gain".
This year I am holding steady and that is a success. I'm a bit more conscious when it comes to eating than I have been in years past but what I've added is riding my bike. With all the practices and college stuff my son is doing I'm not as consistent as I would like but it all has a positive impact.
At the end of July tournament season is over. I will be able to ride more consistently and continue to make forward progress.
