CrankTunes

Cycling is a great activity. Along with the exercise, you get to enjoy the great outdoors...except when you can't.
Unfortunately, for many of us, indoor cycling is something we have to deal with if we want to keep our cycling legs.

Others even prefer indoor cycling. For those of us who either choose to or are forced to cycle indoors, CrankTunes is here to make it suck a little less. Using CrankTunes is simple.

Create a new workout and add all the intervals you want to do. You can set your power, cadence, and the length of time for each interval. In addition, you can pick a playlist from iTunes that you want to listen to during each interval.
