My knees felt fine. Just a little twinge here and there.
The night before, the bowling, I was expecting to be incapacitated because of my right arm mouse injury. Instead, I believe the bowling helped! Worked like weights, and presumably the right kind of movement. My arm still hurts but it felt pretty good after that session. This is really encouraging, partly because I think it would be fun to go bowling more often and partly because I feel I can start using weights again and seeing a difference.
