This video was taken Sunday. I am down 50 pounds and I am amazed at the difference I feel on the court. I play almost exclusively doubles and even at my heaviest I never felt like I was unable to get to a ball.
However it now feels like I am able to get into a much better position before having to strike the ball. My footwork feels better because it is easier to move around the court.
Any who, it is not much of a shocker to say that if you take the equivalent of a 6 year old off your back you will play better tennis.
Here is the link.
