Am I missing something here? If you can maintain the I for a 60-minute+ IT session, then surely it’s more L to M than H?
I thought I was supposed to maintain the I for 40 seconds, of every minute, for 10 minutes, then gently pedal for 10 minutes, then do it again. My current HIIT workout looks something like:
10-15 mins warm up, to get out the city to some 'quiet' roads. 10 x 40 seconds high, 20 seconds low, 10 minutes easy pedalling, 10 x 40 seconds high, 20 seconds low, 10 mins easy pedalling, 10 x 40 seconds high, 20 seconds low, 15-30 mins gentle pedalling to get home as I realise I'm faster this time than last, so I'm further away from home than planned, curse that the wind has moved, and ride home.
