Do you have Sky/Cable, if so, there's a half hour exercise programme on the sports channels every morning, Oz Aerobics, its really good, I record it and do it the day after so I can forward through the ad breaks. They do something different every day, some days its yoga or pilates, then its combat, then high impact aerobics, then dancey stuff etc etc - its on a few times a day, 6am I think then 7am and lunchtime.
