What's your favorite sport?

I'm not an athlete, but I practice physical activities a lot during the week.
I like to go running (or simply 'I like running') cycling and walking with my dog! But my favorite sport is soccer!!
I play soccer once every week! Usually on Wednesday.
Unfortunately soccer, like other sports is not (not healthy in what sense? Do you mean because you can get injured? In that case you could say 'it is not always a safe activity) a healthy activity,  sometimes I get injured and I have to stop for (m)any(?) days.

Well done, only very small errors.
