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.
Cardio is a workout but I define cardio as anything that is focusing on raising your heart rate to a certain level. You have to remember that most cardio buffs will just hop on a treadmill and not account for incline or wearing a weighted vest.
Also weight training can have a cardio effect! Consider the kettle bell swing! Both weight training AND cardio at the same time!
