That's interesting. Tennis doesn't strike me as particularly good for any part of the body, especially all that herky-jerky jumping back and forth. But there's no doubt that *any* activity is good. And "alive" coordination with and against other actors in the world is a notch above what I do. There are 3 basic tiers: 1) canalized activity like weight machines or treadmills (or typing), 2) full 4D "space-filling" activity like free weights, calisthenics, or rock climbing, and then 3) engaging a living system like sparring or team sports.
