A recent analysis of older adults aged 60+ found that resistance training significantly boosts brain-derived neurotrophic factor (BDNF) a key protein that helps protect and grow brain cells. Even better these benefits showed up regardless of how long the program lasted or whether participants were male or female, with the strongest effects seen in those with poorer health. Resistance training also led to real improvements in depressive symptoms with high-intensity aerobic exercise combined with short bursts of exertion the most effective workout to quickly spike BDNF levels.
