However, no significant effect of jaw muscle training on masseter and FDI MEPs or corticomotor maps were observed

Research has shown that a 1 hour jaw training does not make masseter muscle more 'relaxed/excitable'.
I only read the abstraction of the article so i have no idea what form of jaw training they use or the more intricate details of the experiments are.
So maybe there is a chance of the paper being not that accurate?

Can any looksmaxxer here share anecdotal evidences about their own masseter trainings and the effectivity of said trainings?
