I'd like to tone up a bit, become a bit fitter, lose a couple of pounds. I can do the food, that's the easy bit. However, I want to incorporate exercise and the only time I can do it is early morning, as in 5 am. I would like something that isn't too jumpy aroundy. I've looked at yoga dvds but ive no idea where to start. I could do with it being around 30-45 mins. Thanks x
