Check this out for a fitness circuit! 300 reps as quick as possible - my PT 'guinea pig' did it in under 11 minutes. The crazy fool! A great interactive feature which I wrote and filmed it. It's a great interactive article - I put the final video on YouTube for readers to watch, try to beat and then upload their own results.
