Powergrid Fitness brought isometric exercises to gaming with the $1,000 Kilowatt peripheral last year. Now the company is making its isometric-exercise-based gaming sort-of affordable with the Exer-station. The Exer-station forces gamers to actually exert force on its controller in order to play games, producing an isometric workout that allegedly "increases the metabolic rate 5X and burns 350 calories per hour." Basically, it's a big joystick with a really strong, adjustable screen and an LCD display, but any device that tries to make gamers healthier can't really be a bad thing. The Exer-station will be available at the end of January and has an estimated price of $200.
