Gym 2006-04-20
20mins of which 5 mins some kind of automatic warm-up + 15mins @ HR=160. Ended at around 180W. The warm-up was really low effort so my heart rate didn’t get anywhere near 160bpm which in turn meant the machine had to cane me at the beginning to bring it up. For the early part I was pushing 300+W, almost certainly anaerobic. See if I can manually get my HR up then switch into the automatic version. 160 was moderately tough, definitely getting older
