Question:

i have really good strokes but i get really really tired. i want to improve my fitness and my footwork on my backhand side.... i cant chase balls when its on the backhand but i can hit almost every ball on the forehand. how do i improve?

Answer:

You are most likely not slow on your feet (and I do say that with hesitation because I could be wrong)...but the fact that you say you have good footwork on the forehand side means you can fix this problem very easily. 

First, you need to start taking slightly smaller steps on the backhand side. This will condition you to begin getting into the perfect position on the backhand side. Smaller steps will help you get into position quickly. 

Next, I think you should be prepared earlier. You may think that there is a big footwork issue, but it may also have to do with a slower than normal reaction time on your backhand side.

Next time you are on the court, you should definitely think about how to react quicker to your opponents shot. If you get real good, you can usually identify where the ball is going when your opponent starts the foreword swing...but we will save that lesson for a different time!

Hopefully that helps.
