Wii Fit is the latest game for the hugely popular Nintendo video console – and it is in massive demand even before it officially goes on sale. The mega brand has enlisted the help of Girls Aloud singer Sarah Harding and marathon runner Nell McAndrew, who ran the London marathon is 3 hours 11 minutes. The pair, and other celebrities, were on hand to launch the new workout program.

Players use a pressure- sensitive balance board to improve their fitness, strength and balance. The game measures body mass index and fitness before a “personal trainer” guides users through activities including hula hoops, slalom skiing and replicating yoga positions.  Check out Sarah Harding Wii Fit photos HERE.

The virtual program coaches you through 40 different aerobic, yoga, muscle and balance exercises. The product launches across the UK on Friday, April 25.
