What is it that top PBA Bowlers know about bowling that average and poor performing bowlers dont?
Their secret is that they practice the mental side of bowling.
Just go to a PBA tournament and watch the faces of the PBA bowlers vs he bowlers in any regular tournament or in your local bowling center.
Watch how they breathe, watch how they move, watch how a bowler in a PBA tournament looks. For the most part they are focused like a lazer beam and they radiate an inner calm confidence.
All of this happens when you have a strong mental game and of course a LOT of physical bowling too.
