Worth pointing out: we have some evidence that high-intensity interval training actually does make your brain stronger, through an unrelated mechanism. HIIT exercise causes muscles to produce lactate, which crosses the blood–brain barrier and induces the expression of brain-derived neurotrophic factor. BDNF is critical to grow and repair neurons, and we can upregulate it significantly by sprinting hard a few times a week. That's good news for those of us with only a few hours a week to work out! Not sure if you get the same benefits from lifting? I haven't researched this in a while so my sources might be behind the cutting edge. https://pmc.ncbi.nlm.nih.gov/articles/PMC6246624/ https://pmc.ncbi.nlm.nih.gov/articles/PMC6246624/ https://pmc.ncbi.nlm.nih.gov/articles/PMC6435829/ https://pmc.ncbi.nlm.nih.gov/articles/PMC6435829/
