The Benefits of the Norwegian 4×4 Hiit Workout
Many people struggle to find time to exercise regularly, but a new type of interval workout known as the Norwegian 4×4 Hiit workout may provide a solution. This workout, popularized by actress Jessica Biel, has been shown to improve fitness faster than traditional steady-pace workouts like jogging or cycling.
The Norwegian 4×4 workout is a form of high-intensity interval training (Hiit) that involves four-minute sets of intense cardio exercise followed by three minutes of light exercise. A typical session includes a five-minute warm-up, four high-intensity intervals, and a five-minute cool-down.
Research Backing the 4×4 Workout
Decades of research have shown that Hiit workouts, including the 4×4 protocol, are more effective than moderate-intensity workouts in improving cardiovascular fitness and overall health outcomes. This form of exercise has been proven beneficial for individuals with type 2 diabetes and cardiovascular disease.
Studies have demonstrated that the 4×4 workout can produce greater aerobic fitness improvements compared to moderate-intensity running sessions. The intense four-minute intervals challenge the heart and lungs while minimizing muscle fatigue, leading to improvements in maximum oxygen uptake (VOâ‚‚ max) – a key indicator of cardiovascular fitness.
Choosing the Right Workout for You
For those with busy schedules, Hiit offers a time-efficient option for achieving health and fitness goals. However, if a 4×4 Hiit session is too time-consuming, alternatives like the 10×1 Hiit protocol or sprint interval training can be considered.
While Hiit workouts can deliver rapid results, it’s important to choose a form of exercise that you enjoy and can sustain long-term. Consistency is key to achieving lasting fitness improvements, so finding a workout that aligns with your preferences and goals is essential.
Ultimately, the Norwegian 4×4 Hiit workout is just one option among many for enhancing your fitness level. Whether you prefer high-intensity intervals or steady-state workouts, the key is to find a routine that works best for you and fits into your lifestyle.
