Training Load (TL)

Training Load (TL) in Xert represents the accumulated strain from recent training, calculated as an exponentially weighted moving average of daily Xert Strain Score (XSS) values. It reflects how much stress your body has adapted to, is shown as a star rating, and is subdivided by energy systems for detailed tracking.

Definition

Training Load (TL) represents the accumulated strain from your recent training.

It is calculated as an exponentially weighted moving average of your daily Xert Strain Score (XSS) values, meaning that more recent training has a greater impact than older activities.

What It Means

Training Load reflects how much training stress your body has adapted to over time. The more consistent and accumulated your training, the higher your Training Load will be.

To make this easier to interpret, Xert converts your Training Load into a star rating shown in your profile. The table below shows how Training Load corresponds to each star level.

Star Count	Rating	Total Training Load
0	Untrained	< 25
★	Recreational	25 - 50
★★	Trained	50 - 75
★★★	Competitive	75 - 110
★★★★	Elite	110 - 140
★★★★★	Pro-Level	> 140

In Xert, Training Load is further subdivided across your three energy systems:

• Low TL (LTL): Threshold system
• High TL (HTL): High-Intensity Energy system
• Peak TL (PTL): Peak Power system

This allows Xert to track adaptations separately across your energy systems instead of blending everything into one score - helping you prepare the right systems for your event and improve your durability.

How It’s Used

Training Load is similar to Chronic Training Load (CTL) in traditional training models, but it is tracked separately across Low, High, and Peak systems. 

Training Load helps determine:

• Your Training Status (Stars)
• Training Surplus & Deficit
• Daily workout recommendations from XATA and XFAI
