Practice safety
Cardio exercise is usually scalable, but excessive load, poor technique or rapid progression can cause pain or injury. People with symptoms, major medical conditions or long inactivity should choose an appropriate starting level.
Cardio exercise repeatedly loads the cardiovascular, muscular or neuromotor systems. Adaptation depends on the exercise mode, effort, total weekly volume and progression rather than the label alone.
