Here is what Suffering looks like. Andrew, based in Germany, sent me his heart-rate profile chart after doing Fight Club. It gives you a pretty good sense of what you’re in for if you’re doing the workout. You can see the nice warm-up, then the rather moderate first lap (look how long it takes him to get his HR up, though!), then the four serious laps of racing – all with a HR above 170! And why aren’t the tops of those bit efforts flat? Because of all the surprise attacks – and you can see that Andrew was working incredibly hard on those (and after them) – especially lap 5 during the final couple of attacks and the sprint for the win! Whew. Makes me wince in pain just looking at it.

I’ve not loaded my HRM yet but whew I think this guy put in a killer effort… Glad I was not in the room with him!
