We go with Stephan to do some sprints at a nearby park here in Copenhagen. Emmet gets lost along the way because of Stephan’s poor directions, but eventually finds Stephan so he can explain to everyone how the sprints work. The idea is that Stephan is trying to run as fast as he can to train his fast twitch muscles, so you shouldn’t be pushing yourself until you get tired, but just train your muscles’ nerves so they “fire” faster.
