Since your commute is killing your time, and your car (assuming you're not commuting on a train) - consider staying in a hotel near work with a workout room a few times a week. You basically save your commute from and to work, giving you 3 hours back with which to workout, and with the savings to wear and tear on your car, and the gas used, it'll at least subsidize the hotel stays. Canceling an existing gym membership might also drop the total cost to where so many hotel stays a month becomes a monetary wash. Anyway, with working so many hours, you can probably afford to spend a bit on fitness.
