Tennis swing on the strong side of the body?

Answer 1

This is most likely your side that you use the most. If you are right handed you will very likely want to use the right side of your body more when playing tennis.

Also, repetitive use of one side of your body can unequal muscle development, it is best to train both sides of your body.
