Nike+ has already given iPod Nano owners a number of ways to turn their music player into an instrument of torture, and now more are on the way – it's in talks with a host of gym equipment manufacturers to let you use the system in your gym.
From this summer Nike+ compatible treadmills, bikes, stair climbers and other devices used in previous eras to extract confessions will be appearing in gyms. You'll just need to plug your Nano in and it'll record your progress, which you can then upload to the excellent Nike Plus website (an example of the slick interface is above).
It's a clever move by Nike, although it remains to be seen how many UK gyms will install the equipment – Virgin Active Health Clubs are the only UK gym group confirmed to be hooking up with Nike.
Competition for Nike+ is also on the way – I'm going to the launch of a joint venture between Samsung and Adidas tomorrow, which is rumoured to be a phone with similar capabilities. Look out for my hands-on review.
