A NEW lig stretch...maybe?
alright, you get rock hard, then place your hand ,palms down, on the top of your unit and push down towards the floor, hold a few seconds, release and repeat. For a bigger challenge, you should do a kegel while pushing it down for added resistance.
Is this a new strech? If it is, im gonna name it the “GoStretch”, hehe. If its not, kindly enlighten me.
