Ok, I will check out you tube on how to do it properly! I ran my little heart out and managed 7:35! Pretty happy, I know I will smash it up next time as I had two 90 second walks in there, and a third 60 sec walk. I can definitely go harder next time! Also managed 3500 row in 19 mins, did a zumba class, half of a very odd fitball class which was basically zumba sitting down, and another k on the cross trainer. Very sore and tired now!
