So here we go, I know she doesn't think it, but I do quite a lot of music for my wife, whether she listens to or not. This is a good example. She was having to walk into work every day, so I said would you like me to come up with a set of music that, if you keep in time to the rhythm you'll have a pretty good work out? Took me about 4 months to get this together. By the time I had it ready for her she'd got another job that needed a car, so she never used it. Bugger. I think it's pretty good and if you do try and keep time whilst exercising you'll be pretty knackered by the end of it.
