Takara Tomy, Japanese toymaker and creator of weird and wonderful accessories such as this has come up with a cross between a Wii and a personal trainer. Plug the Minute Gym into your TV, input your personal details — including your body fat — and you've got one hundred million different three-minute workouts to do.
The Minute Gym is a tad more portable than the Wii, and weighs just 10 grams (about one third of an ounce. There are a bunch of cute fitness-instructor avatars — including the obligatory over-pumped gym bunny, as well as a dog and one called, rather alarmingly, Sexy Julia — and it runs on just three AAA batteries. Cost is $73.
