Quick question

Hi!! I had this question for a very long time and i hope you guys have the answer to it,
Does ball go before body? Many people say that ball and body have to moving at same time to get power and fluidity into your shot, whilst others say that moving ball before body gets you more power.
Which is the right attitude?

It depends. Typically with a one motion shot, the ball rises as knees bend. This is the correct timing for a quick one motion shot.
