What fresh hell is this? Why is he smiling? I take back everything I said about medicine balls – this is now the most challenging exercise I’ve tried in my 31 day challenge and all it involves is standing and raising a leg. Who knew that a single leg raise would be so hard? If you don’t believe me, if you’re thinking “I’ve hopped before how hard can it be?” then, let me assure you, this is not hopscotch, this is torture. And then he says “turn your head to the left” and the next thing you know, you’re toppling sideways faster than a skyscraper attacked by Godzilla. Try it and see if you can stay upright for 12 minutes, I couldn’t!
