Bike trainer today – a workout I’m going to call the 5:2 because, well, the main set is 5:00 hard followed by 2:00 easy. Today I managed four in a row followed up by 3 x 1:00 very hard/30 seconds easy.
The 5 minute intervals were pretty hard; building to a HR of 160+ within 90 seconds and ending up at about 163-165… They were in fact so hard that I bagged the original plan of capping it off with 5×1:00/00:30.
Next time I do the set I WILL do:
3 x 00:30/00:30
5 x 5:00/2:00 @ HR > 160
5 x 1:00/00:30
