What is your current status stars count? (Training Load)
That determines which workouts are recommended. Example, 3 stars = 3 diamond workouts.
Depending how much historical data was synced, it can take several weeks of activity data to dial in your signature values. If you want to scan your activities for any power spikes, select Activities, Table, then Edit Columns button at top. Add Max Power and sort your list by that column. If you notice any unusual spikes tick those rows, then select the Flag button in upper right. That will exclude those activities from signature calculations, but still include the training load.
If you set a TED (target event date) the recommendations will be endurance based (<TP) for number of weeks due to the phased progression logic in XATA.

With Continuous ATP you’ll get a variety of high intensity workouts for selected Athlete Type (Focus duration) when form is fresh and endurance level workouts (easy and “hard” below TP) when form is calculated as tired.

You can experiment with VO2max workouts by selecting a workout with lower difficulty rating (diamond count). For example, if you search the library for “VO2” you will find two series of workouts. One called Closer and the other called Elastic Heart (hard start intervals). Both use SMART intervals tied to your fitness signature. If failing Closer 170 (3-1/2 diamonds), try one of the 3.0 versions next time. Or failing Elastic Heart 3.5 try 3.0 next time.
When scanning the recommended list of workouts you can tell how intense a workout will be based on the thumbnail chart and how often MPA line drops down and how far. Also the shaded portion indicates what level difficulty/fatigue will accumulate.
Don’t be discouraged if you have to dial down intensity to complete some intervals or switch to Slope mode and tackle the interval as best as you are able. The end result will likely meet the strain ratio target intended.
