At our local community college there is a Phys Ed Dept. program that offers financial incentive for participants to exercise at their choice of several locations, whether at the college, the local municipal gym or a private fitness center. Registrants are actually reimbursed a dollar or two every time they clock-in a certain time working out. Frequent fitness devotees can recover a substantial portion or even all of their club membership fee. I can't recall whether it's state-funded, but I think I read in the news the program was pioneered by Stanford University to encourage exercise and is now gaining popularity in many communities throughout California.
