If you're looking for a low impact game but you still want it to feel like squash then why not try playing half court squash?
This variation of the game is identical to squash apart from one key point; the ball is not allowed to bounce twice before reaching the short line. This has the effect of pushing the game to the back of the court which tends to lead to longer rallies but without the punishing lunges to the front of the court.

Just remember, your second bounce has got to land behing the short line and the line itself is out!
