Introducing: Nike Training Club.

I have a hard time understanding why everyone doesn't love Lea Michele as much as I do, but even if you don't have a soft spot for Glee's resident diva, I think you'll like this app that she's currently talking up. It's called Nike Training Club and it basically just has loads of exercises that you can organise into full-body workouts with instructional videos and audio cues. Plus, you can set your workouts to your favourite music tracks. It's all kinds of awesome, but the best bit by far is it's free. Seriously, yours for nix. On Nike. As long as you've got an iPhone 4.
