Muscle as a Metabolic Organ
- Muscle acts as a metabolic organ releasing myokines that regulate inflammation and metabolism.
- Healthy muscle contraction leads to the secretion of over 600 peptides that promote overall health and longevity.
Strength Training Boosts Brain Health
- Resistance training boosts brain-derived neurotrophic factor (BDNF) enhancing neuroplasticity and neurogenesis.
- This improves cognitive function and memory, especially in the elderly with cognitive decline.
Start With Simple Full Body Workouts
- Beginners should do a full body resistance workout one to two times a week focusing on major muscle groups.
- Use simple exercises like squats, pushups, rows, and lunges to build strength safely.
