I've just started the program after a selection of health issues over the last few years which on top of everything else have seen me put on a fair bit of weight.
I'm not really confident about doing this outdoors so have been using the treadmill in the gym. It seems to be a bit tricky getting the speed up and then down to fit the instructions but I think I'm getting there.
I've just completed the 3 runs in week 1 which were pretty tough. But at least I got there.
I guess my main concern is about what is a reasonable speed. At the moment I'm setting the treadmill to 6.5kph for the brisk walk and 7.5kph for the jogging sections. I can cope with those speeds and they are also not so far apart that I lose a lot of time adjusting the speed.
I'd love to hear from any other people using treadmills to see how they are getting on and what speeds they are using.
