New Year's Resolutions That Last: A Cardiologist's Take on Fitness Goals

Every January, gyms fill up, we break out new sneakers, and many of us set goals to exercise more and “get healthier.” Exercise is one of the best gifts we can give our hearts but understanding how exercise helps your heart can make those goals easier to stick with and more effective.

Consistency Matters More Than Intensity

Your heart doesn’t need extreme workouts or boot camps to get stronger. What it responds to most is regular movement over time. When you exercise consistently, your heart muscle becomes more efficient, each heartbeat pumps more blood with less effort, and your resting heart rate and blood pressure gradually come down. Think of exercise like compound interest for your heart. Small deposits made consistently grow far more than occasional big splurges.

Exercise Shrinks Harmful “Deep” Belly Fat—Even Without Weight Loss

Not all body fat is the same. Visceral fat—the fat stored deep in the abdomen around the organs—is especially harmful to the heart. This type of fat releases more inflammatory chemicals can worsen blood sugar control, and raises cardiovascular risk. Aerobic exercise is particularly effective at targeting visceral fat, which why people can improve heart health even if the scale doesn’t change.

Exercise doesn’t just “burn calories”—it changes how your body handles cholesterol. Specifically, it can lower triglycerides, raise HDL and improve how LDL cholesterol is processed in the bloodstream. Finally, exercise trains more than just your heart—it trains your blood vessels. With regular activity, blood vessels become more flexible, and the lining of arteries releases more nitric oxide, a natural vessel relaxer. The result is lower blood pressure at rest and during stress.

Start Where You Are and Build Gradually

Your heart adapts best when exercise is challenging but sustainable and increases slowly over time. Walking briskly, cycling, swimming, or light jogging are all excellent starting points. You don’t need to be exhausted for your heart to benefit. Strength training and flexibility or mobility exercises complement aerobic exercise by building muscle mass, and improving balance and metabolic health.

One of the fastest ways to quit exercising is to compare yourself to others—or to your past self. Start where you are, and not where you think you should be. Additionally, your heart likes variety. Doing the same workout every day can lead to boredom and overuse injuries. Mixing things up helps both your body and your motivation.

Pay Attention to Your Body

Exercise should make you feel better overall. But listen to your body, as it will keep exercise safe and sustainable. Stop and seek medical advice if you notice new onset chest pressure or heaviness with exercise, unusual shortness of breath that is out of proportion to activity, or dizziness or fainting during exercise

The Takeaway

You don’t need perfection—or extreme workouts. You need consistency. This year, aim for movement you can repeat week after week. Your heart is built to adapt, and even modest, regular exercise can lead to meaningful, lasting benefits.
