It depends on what level you want to hire, preferably professional. I invited it too. It seems useless to be an impostor. If you ask for a little professionalism in the book, it will be different. You will also say a lot of details and do a lot of actions he has experienced personally. The actual effect is better, such as 170~200. It is better to suggest twice a week, because once a week can make muscles and bodies adapt. Too few muscles are not easy to expand and lose meaning and effect.
