No Pain No Gain
Not sure I had correctly anticipated how hard it would be! I have to admit my legs feel better for it - but my chest isn't too happy and I've started coughing. Perhaps excersize isn't such a good idea after all!! It made me realise that I haven't done any excersize in a long time (probably since leaving uni the first time) that actually pushed me hard.
Might go again. Might not. Finding it so hard probably indicates that really I need to.
