New research published in the Journal of Physiology found 6 minutes of high-intensity exercise boosted BDNF levels by 4-5x.
It was done on a stationary bike: 6x 40 seconds on (100% effort), 20 seconds off (25% effort).
Tack it on the end of a gym session for better brain formation, function and memory.
