Because of my knees, I cannot really jump. I mean I guess if my life depended on it, I could do a few jumping jacks, but not well or pain-free. However, I could not resist laundry day’s unmade bed. My inner child forced me to climb up and start “jumping.” The hubs documented (because he wouldn’t join in) and I “ran” and “jumped” around until I just had to “fall” down. It was pretty fun and totally recommended for adults. Kids should probably ask permission first.
