We recently added three new swim workout categories to the workout database. Initially, we had only a stroke category for all stroke swim workouts. We added a backstroke, breaststroke, and butterfly category. We then went through the 177 stroke workouts, and if we saw fit reassigned them to the new categories. Going forward, if the focus of the workout is a backstroke, breaststroke or butterfly set, please categorize it as such. If the workout is a mix of strokes, then the stroke category should apply. Thanks to Cyber-Dynoswimmer, Greg Rasmussen for the suggestion.
