I loved squash through undergrad for exactly those reasons - structured, high intensity, fun, low time commitment. But I couldn't call it low-impact; I don't play today because I found the game had too much stop-and-go and heavy direction changes and it was killing my knees and ankles :(

Maybe I should have said lowER impact (compared to most sports, soccer, etc). I regularly play with some older folks - and they don't move around so much... they make ME do the moving!
