Understanding Xert Fitness Signatures and Improvement

General
1

Hey everyone,

I have been using Xert for a few months now and really enjoy how it tracks my fitness with the Fitness Signatures. However, I am still trying to wrap my head around how to interpret the changes in my Fitness Signature over time, particularly the changes in Threshold Power, Peak Power and HIE.

Can someone explain in simple terms what it means when these metrics go up or down: ?? For example, if my Threshold Power increases but my HIE decreases, how should I adjust my training: ??

Also, are there specific workouts or strategies within Xert that are best for improving certain aspects of the Fitness Signature: ??

I am aiming to boost my overall cycling performance…, but I want to make sure I am focusing on the right areas.

Any tips or advice from those more experienced with Xert would be greatly appreciated! I also read this thread https://forum.xertonline.com/t/how-to-tell-xert-my-fitness-signature-is-too-high-azure-admin/ but couldn’t get the solution to my query.

Thanks in advance!
:pray:

Have a look on YouTube for the Xert Academy videos. About 12 of them, all good viewing.

Episodes I1 and D3 might be the most relevant

Check your power duration curve

TP, HIE & PP define your current personal variant of that curve:
TP is the X value at 1h
PP is the Y axis at 0s
HIE is the area under the curve between X=0 and X=1h

Your kind of training can influence the future shape of your curve.
Sprint focused efforts inclrease PP, efforts around LTP…TP increase mostly that, efforts in between (around 5min power) have highest impact on HIE.

What you should focus on depends on your current goal, like excel in a particular race format (XC, GF etc) or even a specific course or the phase of an ongoing periodization, catch a certain KOM, work on your weakness/strength, improve health etcetc.
