> I'm not good at lifting weights or running, so my thinking is the only thing I have
I'm not saying this to be snarky, but maybe it's time to work on lifting weights and running. The worth of a novel is, of course, subjective, but most people would judge it based on the entertainment value it provides and not how much human effort went into it. Hobbies like fitness (which don't have an output that's meant to be consumed) seem like a safer harbor in this new era.
I was going to say, neither of those forms of exercise are expressions of a natural talent... they're things you simply do (at whatever levels you can currently manage) to stay healthy. They're good for your mental state, too! (And I could stand to do both a bit more regularly...)
