1. Introduction
Thank you for choosing the Myoslim EMS + Inner Ball Roller Body Sculpting Machine. This instrument is designed to provide effective body shaping, muscle stimulation, and cellulite reduction through a combination of Electrical Muscle Stimulation (EMS) and mechanical compression micro-vibration with infrared treatment. Please read this manual carefully before use to ensure safe and optimal operation.
1.1. Product Overview
This instrument is a two-in-one body shaping device, primarily composed of a main machine, an EMS handle, and an inner ball roller handle. It is designed for general human body shaping.
1.2. Working Principles
1.2.1. EMS Handle Principle
The EMS handle utilizes HI-EMT (High Energy Focused Electromagnetic Waves) technology. This technology continuously expands and contracts muscles, performing extreme training that deeply remodels the internal structure of muscles. This process leads to the growth of myofibrils (muscle enlargement) and the generation of new protein chains and muscle fibers (muscle hyperplasia), thereby increasing muscle density and volume. The intense muscle contraction induced by HI-EMT technology can also trigger significant fat breakdown, where fatty acids are decomposed and released from triglycerides, accumulating in adipocytes. High levels of fatty acids cause fat cells to die and be naturally excreted by the body within weeks.
1.2.2. Inner Ball Roller Handle Principle
The inner ball roller handle employs a non-invasive method combining mechanical compression micro-vibration with infrared treatment. The mechanical compression micro-vibration principle involves a ball rotating 360 degrees along its axis. This rotation and rolling generate compression micro-vibration. As the ball rotates and exerts pressure on the skin, it creates a "pulsating compression" effect, facilitating continuous push-pull and kneading motions. This process gently and effectively tightens skin tissue without causing damage. The infrared therapy component releases infrared rays, promoting cell metabolism, enhancing oxygen-blood combination, reducing cellulite, and alleviating muscle stiffness and soreness, ultimately promoting cell activity and reshaping the body.
1.2.3. Benefits of Inner Ball Roller Handle
- Reshapes body contour and smooths wrinkles.
- Enhances muscle toughness and tightens skin.
- Improves blood oxygen binding degree and relieves muscle fatigue.
- Reduces toxins through lymphatic drainage.
- Promotes blood circulation and cell metabolism.

Product efficacy: Gain muscle, lose weight, scientific slimming, lazy fitness.

Inner Ball Roller Working Principle: Non-invasive mechanical compression micro-vibration plus infrared treatment, reaching various tissue depths.

- An LED display on the handle shows the current speed.
- The roller handle includes a key for controlling start or pause.
- The steel balls are flexible and smooth, providing effortless and gentle rolling without stinging, ensuring smooth and even pressure for optimal massage and lifting results.
- No need for the user to massage hard; operation is simple and safe.
