Norwegian 4x4 Cardio HIIT! I have a new one out on my YouTube channel today! I have it linked in my stories so be sure to join if one of your targets is to improve your VO2 max. In the workout, we work intensely hard for four minutes. You could use the simple cardio ladder that I have here or you could hop on a treadmill, a bike, or whatever you have, and work between 80-90% of your max heart rate. Then you recover for 3 minutes, bringing heart rate back to that 60-70% of your max heart rate. Fo
