Cardio Tennis

Since Instapundit has been fitness blogging and my post on weight and mortality stirred up some comment, I thought I would put in a plug for my new exercise class.  My wife talked me into signing up for a 1-hour class called cardio-tennis.  Basically its a group tennis lesson, but with very little instruction.  Instead, the instructor hits three or four balls to me, typically running me all over the court.  Then I jog around to the other side, pick up my 3-4 balls and put them in his basket, and go back to the other side to wait my turn.  With the right sized group, I am jogging constantly and I get a fair amount of practice on my tennis strokes.  Its exhausting but it beats the hell out of jogging.
