So I've joined the gym and as I'm paying for it I figured I might as well go in and use the treadmills as well as going to the classes. I found it so much easier running on the treadmill but I'm not really sure why.. I never used to be able to run on a treadmill but I was walking at speed 5.8 and running/jogging at speed 8.0. I was thinking that I might have been going too slow but when adjusting the speed I found it was my comfortable speed so maybe eating healthily and exercising is just making me fitter and more able to keep up with the programme but I don't know Running on a treadmill is okay right??
