Has anyone tried this? On the back of the5:2 diet, Michael Moseley has co written Fast Exercise which is basically about high interval training.
I'm pretty fit, run and do aerobics but I'm up for a new challenge and think it would be fun to try it and measure the results.
Being January there seems to be lots of articles about the benefits of this method and it would be very nice to get the same results for little effort!
Would be interested to hear anyone else views.
