The headline is broadly defensible, but the qualifications matter. Effect sizes vary by population, the strongest claims rest on shorter trials, and credible voices push back on how it's typically framed.
as you think about um someone who is a committed exerciser maybe you work out 3 to 5 days a week how much of that time should be spent doing vigorous intensity exercise I would say for VO2 max and other adaptations we're going to discuss including the brain um about half of that

and for those that are committed exercisers if you're putting in let's say anywhere between two to 5 hours of training a week it's it's my opinion that you know you you should probably be doing a lot of a lot of that training or half of that training should be vigorous intensity exercise not only because the voax improvements we spoke about earlier but also because of brain benefits
what about people that let's say they're they're exercising they're doing the committed exerciser right they're 45 days a week yeah um but they they think well I don't you know I'm exercising frequently I don't need to get my heart rate up to a high intensity you know vigorous where you're like 0 85% max heart rate um what what do you think about that is important because in your study at least in the the your intervention people were definitely doing vigorous intensity exercise in addition right
