EXPLORE THE NORWEGIAN 4x4 PROTOCOL IN DETAIL

The Norwegian 4x4 Protocol is founded on decades of sports science research. Each training session involves four cycles of 4-minute high-intensity intervals at 90-95% of your maximum heart rate, followed by 3 minutes of active recovery. This method optimizes your cardiovascular system's ability to adapt and enhances oxygen utilization, a key factor in increasing your VO₂ max.

VO₂ max is the ultimate measure of aerobic endurance, directly linked to how well your body can perform sustained exercise. The Norwegian 4x4 interval training's structured design helps to enhance cardiovascular efficiency, endurance, and overall fitness. Research shows significant improvements in VO₂ max for those who incorporate this protocol into their routines, resulting in better athletic performance and overall health.
