In Trainingym, to add a group activity to a workout plan. Simply enter in the workout you wish to add the group activity to and to the right in the exercise search, select the category "Activity." Scroll down and find the activity you wish to assign. Note: in this list there are other sports activities besides the classes taught at your club. Next drag and drop this activity.
Please note: Sessions (days) are not related to a specific day of the week so unless the class is given everyday, the class/session might not coincide with the day of the week the member chooses to realize the session. Recommendation: When you drop the group activity in the workout plan click on the activity and in the comments area write when the class is taught to help your member plan (seen below).
