http://www.fuzzyyellowballs.comhttp://www.bnpparibasopen.orgOne of the big mistakes many amateur tennis players make is to simply "hit" when they practice. Maybe they work on a particular shot -- the forehand, backhand, serve, etc. -- but outside of that their practice sessions are relatively unfocused.Professional tennis players practice with a purpose. They focus on tactics and their upcoming opponents -- not just technique. If you spend a little time planning your practice sessions -- tailoring them around what you need to work on -- then you'll get much more out of your time on court.This video features hitting clips of Gael Monfils, Ana Ivanovic and Roger Federer from the 2009 BNP Paribas Open in Indian Wells, CA.
