The programs are 20-70 minutes, and they include several different songs, depending on the pace required, and continual coaching from the trainer. The iTread programs, for example, tell me when to adjust my speed and/or my incline, so I get a great workout with interval training.
According to iTrain, with an MP3 player you can now download customized workouts with a personal trainer. The downloads are set to music and combines modern technology, entertainment, and health in a portable format. It doesn't matter what kind of workout you enjoy, iTrain seems to offer a program. There is iTread, iCycle, iClimb, iStrength, iSculpt Traditional and iSculpt Ballet, iStretch, iTeenTrain Hip Hop, iTeenTrain Kick Boxing.
Anything that helps me get to the gym and workout is a good thing. With these programs, I feel I am getting more out of each session. I am hooked.
