Off the wagon or the treadmill
Neither yet tho
I've got to admit it is one of the funniest things when you see someone being hurled backwards of a treadmill - never fails to make me laugh - then I struggle not to fall off as well.
Oh yeah, the incline bit can fun as well.
I tried the "cardio" setting one time, never again - somehow or other my weight/age/etc combination confused the damned contraption, and it started to achieve the vertical, whilst telling me to walk/run faster. Mrs Tel was wetting herself with laughter and I was hanging on for dear life, too scared to let go to hit the stop/slow button - never again.
