You now know that signalling is keeping our brain healthy. But did you know that with enough stimulus we can create new brain cells?!
There are certain hormones like BDNF and HGH that help to create new cells, create new synapses, make new brain cell connections and learn new things. There is a whole science behind how hormones like BDNF help with neuroplasticity.
And the key here, is that you make these hormones, in proportion of the intensity of the exercise. Doing weight lifting, HIIT, sprinting are the type of activities which carry such an internsity that require from your mind to be also focused, create new connection and help your body to get better.
