Commercials are unbearable enough when I’m elbow-deep in a bag of pretzels and half-drunk on 24oz cans of Coors—if I had to sweat out extra wattage on a trainer to get through them I’d vow too many boycotts to survive in the city.

Building the torture machine will set you back about $450; so about the cost of that gym membership that was automatically renewed on your credit card on 1/1/09.
