Why Heart Health Gets Its Own Month

February is recognized as American Heart Month, an initiative led by the American Heart Association to raise awareness about the leading cause of death in the United States: cardiovascular disease.

Heart disease rarely appears suddenly.
It develops gradually, influenced by long-term patterns in physical activity, body composition, blood sugar control, blood pressure, cholesterol levels, sleep, and stress. While genetics play a role, lifestyle factors account for a significant portion of cardiovascular risk.

Public health messaging on heart health has traditionally emphasized aerobic exercise, such as walking, jogging, or cycling. These activities are beneficial and should be part of a healthy routine. However, growing evidence shows that resistance training plays an equally important—yet often overlooked—role in cardiovascular health, particularly as we age.

The Physiological Link Between Strength and Heart Health

Heart health depends on more than the heart muscle alone. Skeletal muscle plays a key role in metabolic health, serving as a significant site of glucose uptake and energy expenditure.

As adults age, they naturally lose muscle mass in a process known as sarcopenia. This loss accelerates after age 40 and can contribute to insulin resistance, slower metabolism, increased fat storage, and higher cardiovascular risk.

Regular resistance training has been shown to:

• Improve insulin sensitivity and blood sugar regulation
• Lower resting blood pressure
• Improve lipid profiles, including HDL (“good”) cholesterol
• Reduce visceral fat, which is strongly associated with heart disease
• Improve overall cardiorespiratory efficiency during daily activity

Physiologically, a stronger muscular system reduces the workload on the heart during everyday movement.

What Happens When Strength Training Is Absent

Adults who rely exclusively on aerobic exercise often maintain cardiovascular endurance but still experience a decline in muscle mass. Over time, this imbalance can have unintended consequences.

A lack of resistance training is associated with:

• Progressive muscle loss and reduced metabolic rate
• Higher blood sugar levels and poorer glucose control
• Increased abdominal fat accumulation
• Reduced physical capacity and fatigue during normal activities

As strength declines, even routine tasks require a higher percentage of maximal effort. This can increase cardiovascular strain during daily life and reduce overall activity levels—both of which negatively affect heart health.

Strength Training Is Safe, Effective, and Adaptable

Resistance training is not limited to athletes or experienced exercisers. When properly scaled and supervised, it is safe and effective for adults of all ages and ability levels.

Programs can be adjusted for joint health, medical considerations, and current fitness levels. Research consistently shows that even modest, consistent strength training produces measurable improvements in cardiovascular risk markers.

The most important variable is not intensity—it is consistency over time.

Supporting Heart Health Through the Seasons

In a community like Cranford, staying active is part of everyday life. As spring approaches and daily movement naturally increases, a stronger body helps make that activity more efficient and sustainable.

American Heart Month offers a timely reminder that heart health is not built through short-term effort, but through habits that preserve muscle, support metabolism, and allow the heart to function more efficiently over the long term.

Strength training doesn’t replace aerobic exercise—it completes the picture.
