optimal exercise protocols to boost hrv

To support higher HRV, prioritize regular cardiovascular exercise, resistance training, and recovery; use slow, controlled breathing as a practical add-on. The available guidance describes HRV physiology and recovery breathing, but does not give a specific workout-time schedule for boosting HRV.

• Respiratory sinus arrhythmia: Inhaling tends to speed the heart, while exhaling slows it; this inhale–exhale variation is the basis of HRV. 1
• Controlled breathing: Try three to five minutes of deliberately slowed breathing at the end of a workout to downshift the nervous system and support recovery. 2
• Exercise structure: A general fitness template combines regular cardio with resistance training—for example, three cardio sessions and three strength sessions weekly, adapted to your capacity and schedule. 3
