Spent the afternoon in Bath with writer Peta Bee and fitness trainer Steve Barrett. I was commissioned to photograph Peta trying out the very tough Tabata exercise regime. Despite the smiley picture Peta who is an experienced Marathon runner found this type of 'Supra' Aerobic training very tough. Put simply the idea is to get to maximum heart rate quickly and try and stay there for four minutes with very intense short duration circuit training. Quite literally not for the faint hearted.
