Too much cardio is said to sway pink and only cardio sways pink. My thoughts on exercise to sway blue is whatever it is that raises testosterone such as; lifting, competitive sports, workout videos that make you push yourself, and kick boxing. I attempted to keep my cardio at 30 mins (if walking and running) and then added sets of weights or 15 mins of kickboxing. Lastly, I kept my workouts between 2-5x a week- 5 if it was workout videos.
