Let the trainers take the strain

Been trying to do 10,000 steps per day and to cap it all went to my first " spin " class this morning . Glad to see some old fellows to keep me company including an old mate from school. Thought I'd had enough after the 10 minute " warm up" but managed somehow to get to the end in one (sweaty) piece. I suppose its doing me some good. My trainers however are feeling the strain and looks like its time for another pair!
