If working out alone is getting stale, but you can't make it to classes because of your schedule then i-TRAIN might just be for you.
The website offers a variety of workout programs as pod casts for you to down load to your i-pod or MP3 player. Try iTREAD for your treadmill time or iSCULPT ballet to get the backside of a ballerina. But as the site says, "Put your trainer in your pocket and change your body."
i-Train's offerings are definitely cheaper than a personal trainer. You can subscribe to 5 workouts per month for $9.99, or 3 workouts a month for 12 months for $49.99. Or if you want a variety of workouts or just to give the site a try you can purchase individual sessions for only 99 cents.
I admit, I am bummed that they don't have an elliptical program and I think the more dancey routines might be a bit difficult to follow without visuals.
