ok so some of you know i had surgery a couple of months back, all recovered nicely and so on, but during the month or so where i could do near nothing, i put on 6kg (or 15lbs if you are that way inclined). A month laying on a mattress eating has predictably gone straight to the gut. So this week I started stair running, every morning I have been running about 600 steps (from basement to rooftop of my building is about 120, i do it five times) I think I should mix it up a little though, do some conditioning, so what do you guys think of this circuit I found on the BBC website and this one on Askmen. I want something I can do in sorta 15, 20 mins, since Ill do it in the morning before work, and Im not so good at that early morning thing... Any other suggestions. Priority 1 is some cardio to burn off the fat, but I want to get some all round better conditioning as well.
