On the topic of exercise, here’s one that doesn’t cost more than a box or two of colored chalk and some knee pads to get down to draw it. Some kids had already done that for me and any other sidewalk users.
I did it, much to the amusement of passing motorists 😃
I wasn’t very fast, and missed the mark a couple of times and was sweating when I finished. But I did it! Yay!
