A new vibrating exercise bike has been launched by the company behind the popular Power Plate - an exercise platform that vibrates at various speeds.
The powerBIKE, the Power Plate inventors say, combines all the benefits of the plate (improving muscle tone and bone density, for example) with the cardiovascular workout of an exercise bike.
The seat remains static, but the pedals vibrate as if they are wired to a jackhammer.
It is certainly hard work. The harder you push, the faster the pedals vibrate, rotating the wheel in a jagged circle.
"When you walk down the street, and you step on an uneven paving stone, your muscles contract" the Independent quoted Lars Harms, Power Plate's UK academy and education manager, as saying.
"If they didn't, you would fall over and injure yourself. By exercising on an uneven surface, you are activating those core muscles. It makes everything that much more intense," he stated.
Sessions on the powerBIKE should be kept to no more than 30 minutes, but those minutes are the equivalent of far longer on one of those old fashioned, non-vibrating machines.
However, the cost of the bike is far expensive than the normal exercise bike, at 2,995 pounds.
