The third in the Next Level series is Part 2 of the John Summit Essential Mix on Radio 1 Dance, BBC Sounds! This time 30 minutes of heart rate level controlled turbo cycling. All done and ready for a shower in half an hour, take your heart rate up to 90% or as close as you can get it but make sure that when your heart rate monitor says 90% that it’s telling you the truth, how do you feel at 90% of your absolute maximum effort, could you explain how it feels when you’re there? NO!
