I like your post.
What you said is true. Yeah, get in good shape. However, even in good very shape, you will inevitably lose to the class of player that has sound strokes and just whip the ball
. I observe that pros play like this, ie style and mindset.
I know couple of guys at the park playing this way. Their shots are nearly impossible to return. For the park/rec level it's almost universal that these guys do not have to keep their rally more than 5 shots, and yet they always come out ahead of you in point though. I'm training myself to play this style also. It's very liberating.
