The Most Powerful Drug You Will Never Be Prescribed
If exercise were a pill, it would be the most widely prescribed medication in the world. It reduces the risk of cardiovascular disease, type 2 diabetes, cancer, depression, dementia, osteoporosis, and premature death. It improves sleep, mood, cognitive function, body composition, and sexual health. No pharmaceutical comes close to matching its breadth of benefits.
At our practice in Zürich Seefeld, I prescribe exercise as medicine – with the same specificity I would use for any treatment. Because the type, intensity, duration, and frequency of exercise all matter, and one size does not fit all.
What Exercise Does to Your Body
Cardiovascular system: Regular exercise strengthens the heart muscle, improves endothelial function, lowers blood pressure, and reduces arterial stiffness. It raises HDL cholesterol and reduces triglycerides.
Metabolic health: Exercise increases insulin sensitivity by upregulating glucose transporters on muscle cells. A single bout of exercise improves insulin sensitivity for 24-48 hours. Regular exercise is the most effective intervention for preventing and managing type 2 diabetes.
Brain health: Exercise increases BDNF (brain-derived neurotrophic factor), promoting neurogenesis and neuroplasticity. It is as effective as antidepressants for mild to moderate depression and significantly reduces dementia risk.
Musculoskeletal system: Resistance training maintains muscle mass (combating sarcopenia), strengthens bones (preventing osteoporosis), and supports joint health.
Immune function: Moderate regular exercise enhances immune surveillance. However, excessive training without adequate recovery can temporarily suppress immunity.
Longevity: Regular physical activity is one of the strongest predictors of lifespan and healthspan. The benefits follow a dose-response curve, with the greatest gains from moving from sedentary to moderately active.
Evidence-Based Recommendations
Current guidelines recommend at least 150 minutes of moderate aerobic activity or 75 minutes of vigorous activity per week, plus resistance training at least twice per week. But these are minimums. Greater benefits accrue with more activity, up to approximately 300-450 minutes per week of moderate activity.
What We Do: Personalised Exercise Prescription
Health assessment: Before prescribing exercise, I assess cardiovascular fitness, musculoskeletal status, and any conditions that require modified recommendations.
Tailored prescription: Specific recommendations for aerobic exercise (type, intensity, duration, frequency), resistance training (focusing on the major muscle groups), flexibility and mobility work, and daily movement (NEAT).
Goal-oriented: Whether your goal is weight management, cardiovascular health, mental health, longevity, or athletic performance, the exercise prescription differs.
Progressive programming: Starting from your current fitness level and progressively increasing load and complexity to ensure continued adaptation without injury.
Integration with medical management: Coordinating exercise with any medical conditions or treatments for optimal synergy.
Conclusion
Exercise is the most underutilised health intervention available. If you want a personalised exercise prescription based on your health profile and goals, or if you need guidance on exercising safely with a medical condition, book a consultation at our practice in Zürich Seefeld.
