i do have a couple. I've been learning the guitar recently which is a lot of fun, especially when you get down a tone, its so cool.
i also do a lot of weightlifting. I have a good setup at home with some decent weight so i can do a lot of exercises, but cant do deadlifts. mainly because i dont want to damage my floor and dont want to fork out a lot of money for a deadlift platform and also because i dont have enough weight to do it.
i suppose this is a bit of a "consumption habit" but i like learning things, im doing a mathematics degree currently and quite enjoy learning about complex things. and some of the things i learn are applied but some remain just a cool thing you can tell someone about at a party when the small talk ends.
i actually do some woodwork. i dont do it often but quite a few times ive had to DIY something so i can do a new kind of exercise. for example i recently created a little L shape wooden panel (just a small one) to fit in a corner of a room so i shove one end of a barbell against it and attach weights on the other end. then lift up the bar on the end with the weights and do T bar rows. The L panel helps protect the skirting from damage as the end of the bar would continuously scrape against it. the floor is carpet so it doesnt scrape it anyway
