I have a foam ball. It's bigger than a tennis ball and very light, it's mean to teach children. And it's very cheap! When I feel saturated and stuck I bounce the ball against the wall. It's so light that doesn't make any sound. It relaxes me and makes me feel refreshed. Give it a try if you work at home.
