1. Introduction
The Myoslim Portable Body Sculpting Machine, part of the EMSzero series, utilizes advanced HI-EMT (High-Intensity Focused Electromagnetic) technology. This device is designed to induce powerful muscle contractions, promoting muscle growth and reshaping the internal structure of muscles. It also aims to trigger significant fat breakdown through intense muscle contractions, leading to the release and metabolism of fatty acids over several weeks.
Key features include a touch-controlled display for simplified operation, real-time monitoring and guidance during treatment, and upgradeability to meet evolving therapeutic needs.
Indications for Use:
- Improvement of abdominal tone, strengthening of abdominal muscles, and development of a fitter abdomen.
- Strengthening, toning, and firming of buttocks, thighs, and calves.
