How Sweetmyo Works

Sweetmyo AI muscle trainer is an over-the-counter EMS system designed to stimulate healthy muscles through controlled electrical impulses.

Electrical pulses activate motor neurons, which trigger muscle contractions similar to voluntary movement.
By adjusting parameters such as frequency, intensity, contraction and rest cycles, different types of muscle activation can be achieved.


Important:

  • Not a medical treatment device
  • Not intended to treat injuries or diseases
  • For muscle performance and activation only

  • Zip the suit fully and adjust fit to ensure even pressure and stable positioning
