Exercise and the Heart: Finding Your Optimal Cardio Zone

The Science of Zone 2 Aerobic Training

For cardiovascular longevity and metabolic efficiency, Zone 2 training is the gold standard. #

What is Zone 2?

Zone 2 corresponds to a training intensity where your body generates energy almost exclusively through fatty acid oxidation within the mitochondria, without accumulating excess lactic acid. - Target Heart Rate: Approximately 60% to 70% of your maximum heart rate. - The Talk Test: You should be able to maintain a full conversational sentence without gasping for breath. #

Benefits of Zone 2 for Cardiac Patients

- Increases stroke volume (amount of blood pumped per heartbeat) - Expands coronary capillary density, creating natural collateral vessels - Lower resting pulse and resting blood pressure - Improves insulin sensitivity across skeletal muscle Aim for 150 to 180 minutes of Zone 2 training per week, broken into 3 to 4 sessions of brisk incline walking, outdoor cycling, or easy swimming.
