Learn more about the Norwegian 4x4 Protocol
The Norwegian 4x4 Protocol is a structured high-intensity interval training method designed to improve cardiovascular health and increase VO2 max effectively. It involves four 4-minute intervals at high intensity, each followed by a 3-minute recovery period.
It's recommended to perform the 4x4 intervals 2-3 times per week, with at least one day of rest or low-intensity exercise between sessions to allow for recovery.
Absolutely. The protocol is adaptable to various fitness levels. Beginners should start at a lower intensity and increase it gradually as their fitness improves.
No, the protocol can be applied to a variety of aerobic exercises such as cycling, rowing, or swimming, and is beneficial for all types of endurance athletes.
During the high-intensity intervals, focus on maintaining a steady but challenging pace that brings your heart rate up to the recommended level.
You should aim for 90-95% of your maximum heart rate during the intervals. Using a heart rate monitor can help you stay within the target zone.
While the main focus is on cardiovascular fitness, the high-intensity nature of the workout can also contribute to weight loss as part of a balanced fitness regimen and diet.
Long-term benefits include improved endurance, higher VO2 max, better heart health, and increased metabolic efficiency, which can improve overall quality of life.
If the intervals are too challenging, it's important to scale back the intensity or the duration until you build up more endurance. Always listen to your body and consult with a fitness professional if necessary.
