(Pocket-lint) - Nike Fuel, the new exercise currency that the company has created to help sports fans get fit, will be coming to the company's Nike+ SportWatch GPS training watch and other devices already released.  

"From June, you will be able to earn Fuel points using all existing products in the Nike+ family," a spokesperson confirmed to Pocket-lint.

That means users of the Nike+ SportWatch GPS, Nike+ SportBand, Nike+ GPS App and Nike+ iPod will be able to use the devices they already have to measure their daily performance, rather than have to invest in the new Nike+ Fuel Band due in the shops in May.

Nike has also confirmed to Pocket-lint that, from July, you will also be able to earn Fuel with the new Nike+ Basketball and Nike+ Training footwear.

However, the company is keen to emphasise that, while the Fuel system would work with the SportWatch, its main focus is still as a running performance watch: 

"You will be able to wear the Nike+ SportWatch GPS all day and earn Fuel, should you wish. Although the SportWatch is a running performance product designed to be worn when running, while the FuelBand is designed to be worn all day as it is more of a lifestyle product."

The news is likely to be welcomed by Nike+ SportWatch users who perhaps weren't ready to wear both devices at the same time.
