Option 2:

i think this is one of those things where there are a lot of different activites that can work, and whatever feels right to you and is something that you can see yourself for literal hours, is probably something that can give you a lot. A lot of excersises that practive hand-eye coordination seem to incorporate tennis balls for some reason so if you are looking for a generic starting point, I think those are great. F1 drivers use them a lot, my real life goalies use them for both warm-ups and to practice their skills in general so yeah, those are good I think. Also: Video Games! Right? At least that's one of the things we told our parents when we were looking for arguments why we should absolutely be allowed to play more video games and especially that new ego-shooter that just came up. You don't just kill people, but totally practice your spatial thinking and hand-eye-coordination!
