Here's a brief description of the "curl"
In sum, bicep curls for your brain are pretty simple. Identify what you’re doing (inhale, pause, exhale, pause), notice distraction, mentally high five yourself, and actively bring your mind back to your breath — over and over again. This is your mental strength training.
My question is, is this process of noticing and coming back really what's doing all the good? I ask because I remember reading about a study that showed following your thoughts causes more change to your brain than quickly coming back each time. Unfortunately I can't find the article that said this. Am I way off base here?
