I am ISSA certified, its nothing to it and its a wel recognized certificate as well, You dont need a cert to train unless u work for a gym, but if ur freelance training then no one gives a shit so long as you look the part and know your shit, the field is huge here in jersey, all the trainers i know make a living at it and not just a living but live very very well , with nice mortgages and nce cars, jags, and shit, bt like i said it is huge in jersey
