High Intensity Interval Training | Conscious Couples

High intensity interval training (HIIT) is a workout protocol that involves short periods of intense exercise followed by brief recovery periods. This type of training has been shown to be effective for improving cardiovascular health, increasing speed and endurance, and boosting metabolism. HIIT involves exercises performed in repeated quick bursts at maximum or near maximal effort with periods of rest or low activity between bouts. The very high level of intensity, the interval duration, and number of bouts distinguish it from aerobic activity, as the body significantly recruits anaerobic energy systems. With its origins dating back to the 1930s, HIIT has evolved over the years, with various forms of HIIT-style workouts emerging, including those that combine cardiovascular activity with resistance training. Today, HIIT is a popular workout strategy among athletes and fitness enthusiasts, with many gyms and studios offering HIIT classes. According to a study published in the Journal of Strength and Conditioning Research, HIIT can improve cardiovascular health by increasing VO2 max, a measure of aerobic fitness, by up to 15% in just 6 weeks. Additionally, a study by the American Council on Exercise found that HIIT can burn up to 15% more calories than traditional steady-state cardio, making it an effective way to lose weight and improve overall fitness.
