Tag: HIIT for endurance

Cardiovascular fitness, often referred to as cardio levels, is a critical measure of an individual’s ability to perform sustained physical activity. It is determined by the efficiency of the heart, lungs, and blood vessels in supplying oxygen to the muscles during exercise. Many individuals, regardless of their level of physical activity, frequently ask, "Why is my cardio so bad?" Understanding the factors that contribute to poor cardiovascular endurance is essential for identifying ways to improve fitness. Low cardio levels can result in early fatigue, labored breathing, and difficulty sustaining moderate-intensity activities. Without addressing the underlying causes, individuals may find it challenging to progress in their fitness journeys.
