I am on a 3 day split routine (chest and triceps Mondays, back and biceps Wednesdays and shoulders and legs Fridays) with Cardio on Tuesday, Thursday and Sunday.
I am taking some new suppliments (creatine) that have directions to take on “workout days” so I am trying to figure out if cardio days count or just my lifting days.
It is determined by intensity, duration and frequency. A vigorous cardiovascular workout (cycling, running, swimming, etc.) certainly counts as a workout. Why are you counting?
And I would also ask why are you taking supplemental creatine? What is your goal? Is it to enhance your power capability? At best, it’s temporary.
