Exercise is a cornerstone of heart health, offering numerous benefits like lowering blood pressure, supporting a healthy vascular system, and reducing cholesterol. Here, we’ll explore how different types of exercise—aerobic, resistance, and stretching—promote heart health, how they help achieve a healthy blood pressure range, and why stress management, including yoga and adequate sleep, is key to a heart-healthy lifestyle.
The Role of Exercise in Heart Health
Exercise impacts the heart in several ways: it strengthens the heart muscle, improves blood flow, reduces stress, and contributes to weight management (1). Each type of exercise offers unique benefits for heart health:
- Aerobic Exercise: Improves cardiovascular endurance and lowers cholesterol (2).
- Resistance Training: Builds muscle, which can help manage blood glucose and insulin (3).
- Stretching/Yoga: Improves flexibility and reduces stress, which can positively impact blood pressure (4).

Aerobic Exercise: Strengthening the Heart and Lowering Cholesterol
- Benefits: Aerobic exercises, like walking, cycling, and swimming, are some of the best exercises for heart health. They improve circulation, reduce cholesterol, and lower blood pressure (5).
- Ideal Duration and Frequency: The American Heart Association recommends 150 minutes of moderate aerobic activity per week, or 75 minutes of intense aerobic exercise (1).
- How It Works: By raising the heart rate, aerobic activity helps the heart pump more efficiently, leading to improved blood flow and vascular health (6).
Best Aerobic Exercises for Heart Health
- Brisk Walking: Low-impact but highly effective for lowering blood pressure and cholesterol (7).
- Cycling: Increases heart rate while being gentle on the joints.
- Swimming: Provides a full-body workout without high impact, ideal for overall cardiovascular health (5).
-
Resistance Training: Building Muscle for Vascular Health
- Benefits: Resistance training helps build muscle mass, improves blood sugar levels, and has been shown to aid in lowering systolic and diastolic blood pressure (8).
- Ideal Frequency: Strength training twice per week can effectively complement aerobic exercise for heart health (9).
- How It Works: Building lean muscle can improve insulin sensitivity, a benefit for those managing metabolic conditions, which in turn supports vascular health (8).
Examples of Resistance Exercises
- Bodyweight Exercises: Squats, push-ups, and lunges are great for building strength without equipment.
- Free Weights or Resistance Bands: Include exercises like bicep curls, shoulder presses, and leg presses to increase muscle mass and strength.
-
Yoga and Stretching: Stress Reduction and Flexibility
- Benefits: Yoga combines movement with breathwork, which can reduce cortisol levels and manage blood pressure by calming the nervous system (10).
- Why It’s Important: Chronic stress contributes to hypertension by elevating cortisol, which constricts blood vessels and raises blood pressure (10).
- Recommended Practices: Incorporate yoga or stretching routines 2-3 times per week for flexibility, relaxation, and mental clarity.
Examples of Beneficial Yoga Poses
- Downward Dog: Stretches the back and legs, enhancing circulation.
- Child’s Pose: A gentle resting pose that can calm the nervous system.
- Corpse Pose (Savasana): Promotes deep relaxation, ideal for stress reduction.
The Importance of Rest and Rejuvenation
Just as important as exercise is allowing the body to rest. Adequate sleep is critical to repairing and maintaining heart health, as it enables the cardiovascular system to recover. Adults should aim for 7-9 hours of sleep per night to reduce stress, manage blood pressure, and enhance heart function (11).
