A Power Plate workout is intensive and quite taxing, and you will certainly perspire – albeit not as heavily as during an intensive cardiovascular program – especially when you expand the number of exercises or shorten the period of rest in between. You are physically exerting yourself, causing an increase in body temperature and metabolism, which will cause perspiration. The extent of exertion obviously depends on the program you perform – massage, relaxation or stretch exercises will most likely not make you perspire heavily.
