Weight Transfer
 
Many players don't properly understand weight transfer.  When making a strong 3rd ball attack, the player must feel a slight lift with the legs, while predominantly shifting from the right foot to the left, while keeping the legs, core, and upper body low.  Why stay low?  There are dozens of reasons, but the 3 primary ones are to transfer the weight forward instead of up, make solid contact, and to keep the balance for the next ball.
 
Previously, Andrew had a 3rd ball attack that wasn't balanced.  Could he hit it?  Sure.  But the rally afterwards wasn't stable.  In the last couple months, he has developed much better body balance, holding the body lower, and it has had a huge impact on his stroke efficiency and the rally afterwards with 5th ball, 7th ball, and 9th ball.
 
So what about you?
 
Are you thinking long term?
 
Do you want a strong game 3 or 4 or 5 years from now, then start focusing on developing good balance with your 3rd ball attack.  Long term, it will really really really pay off!  Think long term!
