I travel a lot with work and could do with some sort of a workout that I could do in my hotel room. I don't always stay somewhere with a gym and unfortunately siting on my arse all day and then eating hotel/conference type food isn't great.
So, I think it needs to be something that...
... can be downloaded onto my iPad or played on my laptop
... doesn't require much space
... doesn't require equipment (apart from perhaps a hotel towel)
... doesn't include too much jumping around (don't want to get complaints)
Any ideas?
