The repetitiveness would have me get bored instantly… Have you tried bouldering? Every route is different, you have to figure out how to move, which muscles to activate etc…, so you stick to the boulder (wall) and dont fall off. It is so much more rewarding because you not only do a physical activity but also analyse and solve a problem. Might not feel like this for the very beginner problems but definitely later one, once your technique backpack gets a bit bigger. Can highly recommend.
