If it's just discomfort or something that goes away with experience, I say keep going considering you love doing it.

For sports with a problem solving aspect, I'm not sure whether sweeping is the most physical intensive activity, but curling is basically a sport that comes with a fun physics/geometry problem attached. Just don't become a skip if you want the exercise (they don't sweep).

Quanta magazine is actually excellent for math and physics.

I always hared the environment lol. My stubbornness justified.
