Cardio training is a cornerstone of fitness, offering numerous benefits for the heart, lungs, and overall energy levels. It involves sustained activities like running, cycling, or jumping rope that elevate your heart rate and improve oxygen circulation. Regular cardio workouts enhance cardiovascular health, increase stamina, and support weight management.

High-intensity interval training (HIIT) is a popular form of cardio that alternates between bursts of intense effort and short recovery periods, maximizing calorie burn and improving aerobic capacity. Low-impact options, such as swimming or walking, are excellent for beginners or those with joint concerns. Consistency is key to reaping the benefits of cardio, which include reduced stress, improved mental clarity, and a stronger, healthier body.
