Christmas Pudding Burning Intervals

I had passed through the festive season, my waistband expanded and my keenness for exercise renewed after nearly the whole of December feeling unwell and suffering from various bugs and viruses. I decided with another week before I returned to work I would hit the gym or at least exercise with daily regularity to get me back towards fitness. The weather, expectedly chilly for this time of year I decided I would opt for treadmill running, and as this is incredibly dull for any distance I opted for intervals as these not only seem to pass much quicker but they are good for improving fitness.
