I have had the Nike Training Club app on my phone for months but it was kind of lost somewhere. Ysa was very efficiently bossing my phone around a couple of days ago and when she was done, lo and behold, there was the app that I had downloaded and promptly forgotten. (How is it that a 20 month old tiny person just knows how to unlock and navigate iPhone technology?) I decided to try a workout this morning .... LOVED IT!! Lots of options, good voice guidance, timer, video tutorials, bonus stuff.  If you haven't already, check it out. Sadly the app is only for iPhone and iPod Touch.
