Hi, I started using Xert because I like the multidimensional nature of it. The concepts of peak power and threshold power are easy to understand and see the impact because they are easily translatable to w/kg and then easy to see impact on climbing, sprinting, etc.
However, I’m struggling to understand HIE. I have a good feel for what my TP sitting at 320 or 360 may mean for performance, but I don’t really have any concept of HIE other than a bigger number will mean (I think) I’m better and doing, sustaining and repeating efforts above my TP without blowing myself up.
Can someone help me interpret / understand? I’m trying to determine what number I should look to build towards and if I achieve (eg) an HIE of 28 how do I translate that into a performance gain?
Two target events - one a 40km time trial in July, the other a 130km road race in September with 2 decent climbs.
