Hobbies are activities that we do in our spare time (= free time)
Things people play
Note: People join clubs (= become members of clubs) where they can play cards and chess.
Things people collect
With these hobbies we can use two different verbs, go and do:
We often go camping in the summer, or I do a bit of / a lot of rock climbing in the summer.
Note: When we start a hobby for the first time we often use the phrasal verb take up, and when we stop doing the hobby for the final time, we often use the phrasal verb give up.
I took up golf when I was fifteen, but I gave it up last year.
