What do your preteens do in the weekends?

My almost 12 year old son has a pretty active week (schooling, softball, Jiu-Jitsu, chess club, and 10+ hangout, plus he helps with groceries and doing laundry at the laundromat) so in the weekends he likes do to absolutely nothing but watch tv and youtube. Id love to find something else for him to do thats not chores or yardwork. He does do crafting as a hobby (he sells his crafts at markets) but he does that during the week during school time. Hes in to fitness and goes for runs every morning so does keep semi active in the weekends, I just cant find anything that he actually enjoys doing on his own while we do chores and yardwork.
