PowerDot offers an intensity of 1-100 for each of the programs, but it how high of an intensity is all up to you, your comfort level and exposure to stim.
Our Everyday, Wellness, Recovery, TENS and Massage programs should be comfortable during use and you really only need to increase the intensity to the point where you feel and see the muscle twitching. It could happen at 5 or 30 but there is no reason to turn it up as high as you can.
The Performance programs and Potentiation/Warm Up program you want to increase to the point right before it’s uncomfortable (not painful). Think of it as working out, we enjoy the benefits of working out but the stress we put the muscles under while working out is never fun.
