So i’m assuming counterproductive when used prior to sprinting, and on CNS-recovery days?
I agree there’s partial CNS stress during usage (I can tell because I can’t read with concentration during it), but I still see it as an ‘easier’ means to training, because I’m not being ‘forced’ to create the muscle stimulations, as opposed to going out there and making myself sprint, if you know what I mean.
That being said… 200s are much easier with EMS training support (mentally-wise)
