Intensely engaging the lower body triggers a series of extremely beneficial physiological reactions. This is an unexpected factor that very effectively reduces the risk of heart disease through several physiological mechanisms:
Nitric oxide production: Muscle exertion stimulates the release of this valuable gas, which helps relax blood vessels. The result: improved blood circulation and optimal nutrient delivery to vital organs.
Improved vascular function: Strong muscles contribute to the dilation of blood vessels, thus facilitating the pumping work of the heart.
Reduction of inflammation: Greater muscle mass is associated with lower levels of systemic inflammation, and chronic inflammation is one of the main drivers of heart disease.
This is confirmed by scientific research.
Dr. London’s claims are largely supported by recent medical literature. A study published in 2024 in the European Journal of Preventive Cardiology highlighted a very strong link between quadriceps strength and a reduced risk of heart failure.
