Disc golf eh? I took my kids to a park that had a course built in. It took me time to figure out what it was.
I started walking after a few months of pandemic lock down crap. It was a way for me to get some air, and to be by myself. My wife bought me a weighted vest to wear when I walk. It goes up to 40lbs.
I agree with leg day. You do NOT SKIP LEG DAY.
