Is HIIT better than cardio for heart?

Meyer added, “HIIT has been shown to provide better results in cardiorespiratory fitness, and could be thought of as more efficient.” Chokshi and Chris Kusmiesz, MS, an exercise physiologist with the Penn Sports Cardiology and Fitness Program, agreed.

Can you do HIIT with a heart condition?

High‐intensity interval training appears to be relatively safe to conduct in patients with cardiovascular disease, including coronary artery disease and heart failure, within tertiary‐care cardiac rehabilitation settings.

How does HIIT affect heart?

Low-volume HIIT was also shown to improve the heart's structure – such as chamber enlargement. This increases the volume of blood the heart can pump to the rest of the body each heartbeat.

Can I damage my heart by exercising?

Is HIIT same as cardio?

The definition of anaerobic is “without oxygen.” Unlike aerobic cardio that uses oxygen to break down energy stores and produce ATP, HIIT cardio is performed in an oxygen deficit. This means your body breaks down glycogen in the muscles to produce ATP — the energy currency of the cell.
