"If you like the idea of turbo training but you can't stand the monotony then there's plenty of ways to keep yourself occupied, from your iPod to a full VR trainer. But at just €5.99 this 60-minute workout from The Sufferfest is a real bargain, and it's a session you can repeat without it becoming stale." "Needless to say it's pretty intense, and normally where I'd struggle to leave the 160s on the HRM, on this session I was pushing 178 max. The structure of the spiral means that you can really ramp up the effort as the intervals get shorter. So top marks on both counts."
