I agree that it is good to exercise. Walking is the best exercise. You do not need sports. Just get rid of your car. You will have more money to buy Torah books!
I once walked 8 hours in the rain and was good to work out after, walking isn't even exercise for old people, there's a 100 year old guy that runs 20km every morning, it's just pretty. You need to run if you want to touch your abs.
Take the bus instead? Multiply your transport time by 3-10x, no time to study any Torah books, and you'll have less time to make money. You do not need sports, or the virtual reality machine where you think you're flying but it's a super core exercise, but you feel it less than just the treadmill, you're focused on the fun and not the pain.
