[COBI]

As an instructor, my ipod for the gym is loaded with mixed designed for class. They work out great for my personal workouts, too, because the beats per minute is typically faster, the beats enhanced and there are no breaks or fades between songs. My favorites are from www.getfitmixes.com, www.sassyworkshops.com and "Rogue Underground" (http://www.youtube.com/user/Rogueunderground).

The nice thing about Rogue's and the Turbo Kick CDs that I have is the interval/timing; after the warm-up, the songs break at about 2 min, 1 min, 2 min, 1 min and so on. This allows me to do intervals without keeping track of time myself.
