Training Suitability or just Suitability provides a way for you to understand how well a proposed workout, activity, or session fits into your Training Program.  Not only can Xert recommend workouts, but it can further refine why a particular workout, activity, or session is a good (or poor) fit for your training.

Xert does this by evaluating essential information about each workout, session and activity, such as:

Ultimately, Training Suitability is determined by 3 primary factors: Xert Strain Score (XSS), Difficulty Score, and Focus Duration. We’ll outline some of the terminology you might see under your recommended activities below!

Xert Strain Score (XSS)

  • (Very) Productive: XSS of the proposed training is (much) higher than what is necessary to maintain your improvement
  • Good: XSS of the proposed training is roughly equal to what is necessary to maintain your improvement
  • Fair: XSS of the proposed training is just below what is necessary
  • Unproductive: XSS the of proposed training is significantly less than what is necessary

Difficulty Score

  • Very Challenging: proposed training will be very challenging to complete based on your current fitness and training status
  • Challenging: proposed will be stretching your abilities based on your current fitness and training status
  • Achievable: proposed training is achievable based on your fitness and training status

Note: If the workout is a group session, the workouts will be classified as Group Challenging, Group Suitable, or Group Easy

Focus

  • Optimal Focus: proposed training matches recommended focus type
  • Near Focus: proposed training is close to recommended focus type
  • Out of Focus: proposed training does not align with recommended focus type

Lastly, there are some additional tags for our workouts that indicate their suitability, or lack thereof, including Out of ReachBreakthrough, and Not Recommended.

  • Out of Reach: the proposed training cannot be performed; the required power of the workout is significantly higher than your MPA for at least one part of the ride
  • Breakthrough: the required power of the workout just meets or slightly exceeds your MPA for at least one part of the ride
  • Not Recommended: workout is NOT recommended. These workouts are experimental or help highlight the concepts behind Xert. In general, they should not be part of your training.
