Nike Training Club. Best app for iPhone ever! Lots of different workouts to use anytime I want, short videos to show me how it's done and the possibility to choose whicever kind of workout I wanna do: get lean, toned, strong or whatever. Been using it since last week and I love it! And it lets me use my own playlists from my library!
