Weight training benefits cognitive function by improving blood flow to the brain, enhancing neuroplasticity, and potentially reducing the risk of neurodegenerative diseases. Research shows that engaging in resistance training can elevate levels of brain-derived neurotrophic factor (BDNF), a protein that supports neuron growth and survival. Furthermore, weight training improves mood and anxiety levels by increasing the production of neurotransmitters like serotonin and dopamine. This combination of physical and mental benefits illustrates how regular weight training can lead to improved overall brain health and cognitive abilities.
