A recent study found that six 40-second sprints at max effort increased plasma BDNF by nearly 3 times MORE than 90 minutes of light exercise.
BDNF is your brain’s fertilizer—it drives neuroplasticity, sharpens memory, and protects against cognitive decline. It plays a critical role in mental health, mood regulation, and even metabolism.
Higher BDNF levels are linked to lower rates of depression, anxiety, and neurodegenerative diseases like Alzheimer’s.
The study also reveals that fasting for 20 hours does not impact exercise-induced BDNF levels, meaning you can maximize brain benefits whether you train fasted or fed.
So if you only have 6 minutes in your day, make them count—just a few bursts of high-intensity movement can rewire your brain, boost resilience, and protect long-term cognitive health.
