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.
In a word “yes.” A “workout” can generally be defined as any exercise routine. That being said, the concept of a workout is also very subjective and relative to what a person “normally” does for exercise. For example, a marathon runner may NOT consider a 3-mile run for a workout at all, but may consider lifting weights for 15-minutes a real workout. Relatively and subjectivity are the keys when trying to define what a workout consists of.
