To advance this forehand shot further, I would have another squash player stand just behind me or just in front. They would then hit the ball off the front wall, parallel to the side wall, just the same as before, but then I would wait for it to return from the wall, bounce once, then, hit it myself off the front wall so that it returns to the other squash player. They would hit it again continuing the process. This is good to practice because it incorporates some one else into the game and starts preparing me for a real game.
Then to advance the forehand shot further I would ask another squash player if they would hit the ball from the left hand side of the court at an angle, against the front wall, so that it will bounce off the front wall, then off the right hand wall and land somewhere in the back right corner of the court. I would then return this shot on my forehand hitting it somewhere just above the middle line on the front wall and so that it lands in the back right hand corner of the court. This helps improve my fore hand further by preparing me for shots that come from different angles.
Then to increase my range of forehand shots I would ask if another player could play a drop shot against the right hand side of the front wall and so that the ball lands within a meter of the front wall. I would then return this shot, so that it lands in the back right hand side of the squash court. I take place in this exercise to widen the verity of shots I can return and to prepare me for any drop shots an opponent may play during a game.
Then, I would try and incorporate my forehand skills into a small game with my own rules, so that it focuses on testing my improved forehand skills. They would consist of two players, all the rules of a normal squash game will apply, although, my opponent will only be aloud to hit the ball so that it lands anywhere on the right hand side of the court. To win any points I will only be aloud to return the ball to the back right hand side corner of the court. After doing all this practices I should have a much stronger fore hand than I would have other wise.
