Indeed, targeting the legs during workouts significantly increases overall muscle mass, a key factor in maintaining excellent cardiovascular health. This approach is even considered the best exercise for heart health by many medical specialists.
The central role of muscle mass
Dr. London explains that the legs alone represent between 40 and 50% of our total muscle mass. By strengthening these large muscles, the body drastically improves its insulin sensitivity and its ability to regulate blood glucose. These two elements are absolutely essential for mitigating cardiovascular risks.
Insulin sensitivity: Data shows that a 10% increase in muscle mass is directly correlated with an 11% decrease in insulin resistance.
Lipid profile : Developing muscle mass promotes the reduction of triglycerides while increasing HDL cholesterol (the “good” cholesterol), which considerably limits the process of hardening of the arteries.
