Practice On Your Own - How???

So how? Well lets just start with a bucket of balls and go out on the court alone. Decide what stroke- let us say the forehand - so doing a drop bounce hit to start just hit your forehand without any pressure of where- but make sure of your key points contact point-swing-finish and be aware after your shot YOU see how you finish- DO NOT bother about where. Then maybe work your backhand - I am asuming that you know the basic key points of your strokes- there is no point doing this without knowledge of what you are trying to achieve- otherwise you are just practicing your errors.

As you go the other end of the court to collect the balls DONT- pick up each ball where it finished and hit it back down the court as if you where passing it to an imaginary opponent - does not matter where the ball is- pick it up and now decide where your opponenet is and try to pass it to them as you would in a game- but still using the correct technique - use your forehand and your backhand.

Now maybe you can collect the balls once again and this time give yourself a target- example 10 forehands deep crosscourt -then 10 backhands the same - so as you get better at this you may make your target slightly more difficult. Try hitting after one bounce your forehand down the tramline - stand just inside the tramline your end- drop the ball in the tramile and try to hit a 90 degree hit down the line - very difficult.

So you could go on- changing your position on the court- hit crosscourt short angles by moving closer to the net practice taking the ball higher by tossing the ball high in the air and taking for example your forehand at a higher than normal hit point.

Endless ideas and variations - BUT read the below

The next practice session do not think in terms of learning on that day! Think like the pros in terms of giving your body and mind time to learn on a subconscious, automatic level. What you practice today will become part of your subconscious weeks and months later. Your job is not to over-think or judge the daily results. Your job is to keep up the intense practice sessions and allow time to work its magic.

If you could find time a couple of hours a week- I am convinced that as long as you are using the key points your ground strokes will improve.
