Norwegian 4×4 interval training

What is norwegian 4×4 interval training

he Norwegian 4×4 interval training is a high-intensity interval training (HIIT) protocol for improving your cardiovascular fitness and endurance. It’s named for its simple structure:

• 4 intervals: You perform 4 periods of intense effort, each lasting for 4 minutes.
• 3 minutes recovery: Between each interval, you have 3 minutes of active recovery at a much lower intensity. This allows your heart rate to drop back down before the next burst.
• Warm-up and cool-down: The entire session is bookended by a 10-minute warm-up and a 5-minute cool-down at a moderate pace.

The key feature of the Norwegian 4×4 is the intensity during the work intervals. You should aim to work at 85-95% of your maximum heart rate (MHR). This is a hard effort, but it’s what drives the improvements in your VO2 max, lactate threshold, and other important fitness markers.

Here are some of the benefits of the Norwegian 4×4:

• Time-efficient: You can achieve a great workout in under 40 minutes.
• Effective: Studies have shown that it’s very effective for improving cardiovascular fitness and endurance.
• Versatile: You can do it almost anywhere, with no special equipment needed.
• Mentally challenging: The high intensity can be tough, but it can also be mentally stimulating.

However, it’s important to note that the Norwegian 4×4 is a demanding workout. It’s best for experienced athletes with a good base of fitness. If you’re new to exercise or have any health concerns, it’s important to talk to your doctor before starting this type of training.
