Hey /adv/ femanon here, I'm an out of shape shit and I want to get healthy, but working out is the most soul crushingly boring thing I've ever done and it's super hard to get motivated when I'd rather watch paint dry than go to the gym for an hour and do monotonous tasks on the machines in silence.
I figure if I could get into a sport it might make exercising more fun at least.

The only catch is I have a deformity in my knees that keep me from anything that involves putting too much strain on them, very heavy lifting, long term running, and jumping are ill advised for me according to my doctor. I also figure I should try to stick to more "feminine" sports since A.) it's difficult to find coed teams and B.) guys tend to get too competitive for my taste anyway and I don't want to let them down lol.
I'm thinking Tennis, never played tennis before in my life though outside the unit in high school P.E.
I'm looking for something that can help me lose the most weight and be the most active but also fall within those set perimeters.

Or alternatively if you have any tips on making the gym more fun and interesting I'm all ears for that too. Other than just "change up ur routine"
