Now just to see the height difference of velocity curves of cardio on my computer doing nothing '(just before the shower) I go I run I put my pathetic (or I respect the program) but I go out so more willingly although I have no compet provided for within three months. easy to use even for a man of 50 who does not have iphone. it is a fantastic tool that fills me and will save me a few minutes and for longer than a pair of shoes. go for it, it's in your nature
