When you assign a workout to a group or your whole roster, each athlete gets their own copy. Editing or deleting one lets you choose whether to touch just that athlete or everyone.
Edit a workout
Open the workout on an athlete's training calendar and make your change. If it was assigned to several athletes, RapidCoach asks whether to apply the change to just this athlete or everyone it was assigned to.
Remove a workout
Deleting a workout offers the same choice — just this athlete, or everyone it was assigned to — so you can pull it from the whole group in one step or fix a single athlete's plan.
Moving instead of editing
To relocate or repeat a workout rather than change it, use the training-calendar clipboard.
