Aurelio Rojas, cardiologist and health expert: "If you want to lose weight for real and protect your long-term health, you need strength training."

Strength training is consolidating as an essential tool for weight loss and metabolic health , according to numerous scientific studies and preventive medicine specialists. Contrary to the traditional idea of focusing exclusively on aerobic exercises, such as walking , more and more professionals are emphasizing the importance of muscle as a protective organ.

This approach is not limited to body aesthetics but also involves profound improvements in metabolism, hormonal regulation, and the prevention of chronic diseases . Among the professionals championing this perspective on social media and in clinical practice is Dr. Aurelio Rojas , a cardiologist and health educator.

Muscle as a metabolic ally

From his official Instagram account ( @doctorrojass ), Dr. Rojas sends a direct message: “If you want to lose weight for real and protect your health in the long term, you need strength training.” In his post, the specialist emphasizes that the scientific evidence is clear: “Strength training preserves and increases muscle mass, raises your basal metabolism, improves insulin sensitivity and body composition, reduces cardiovascular risk and strengthens your bones.”

The message goes beyond physical appearance. “Muscle isn't just about aesthetics. It's a metabolically active and protective tissue. It's about health,” he maintains. According to Rojas, strength training isn't an optional recommendation, but a clinical necessity in the context of modern medicine: “It's not optional. It's necessary.”

In addition to its physiological benefits, the doctor highlights the positive impact on psychological well-being and systemic inflammation : "It reduces chronic inflammation and improves mood." Strength training can include exercises such as squats, deadlifts, push-ups, or dumbbell exercises, which are essential for gaining muscle mass and protecting health. In this sense, regular strength training becomes a comprehensive strategy for addressing excess weight and other risk factors from a global health perspective, always adapting the routine to each person's abilities.
