Has anyone got one of those walking pads that can go up to 10kph? I've been thinking about getting one for fast walking (and running for a beginner). Space is an issue so thought it might work as it can be pushed under the sofa. I have a cross trainer which I use for a few weeks then become bored so thought it might offer variety. I know I can walk outdoors but when I get in from work, it's late by the time I've put my children to bed. I tend to exercise at 5:30am so need to be in the house as they are asleep
