The Science Behind EMS Kegel Trainers: A Comprehensive Guide

Pelvic floor health is a topic that has gained significant attention in recent years. The pelvic floor muscles, which support the bladder, bowels, and sexual organs, play an essential role in urinary control, sexual function, and overall well-being. Strengthening these muscles can provide numerous health benefits, and that's where the YoniFlex EMS Kegel Trainers come in.

What is the Kegel Muscle, aka Pelvic Floor Muscle?

The Kegel muscle refers to the pelvic floor muscles, a group forming a hammock-like structure at the pelvis base. These muscles support pelvic organs—the bladder, uterus (in females), and rectum. The key muscle in the pelvic floor is the pubococcygeus, often exercised through Kegel exercises.

Pelvic floor muscles play crucial roles in bodily functions:

  • Bladder Control: They regulate urine release.
  • Bowel Control: Assisting in managing bowel movements.
  • Pelvic Organs Support: Providing support and maintaining proper positioning of pelvic organs.
  • Sexual Function: Involved in sexual pleasure and supporting reproductive functions.

Performing Kegel exercises entails contracting and relaxing pelvic floor muscles. Regular exercise benefits both men and women, especially during pregnancy, post-childbirth, or for those with urinary incontinence, pelvic organ prolapse, or sexual dysfunction.

To perform basic Kegel exercises:

  • Identify the Muscles: Stop urine midstream to locate pelvic floor muscles.
  • Contract and Hold: Contract identified muscles, holding for a few seconds (start with 5 seconds, gradually increasing).
  • Release: Relax muscles for a few seconds.
  • Repeat: Repeat cycles several times, targeting a set number of repetitions daily.

Note: Kegel exercises may not be suitable for everyone, and those with specific health conditions should consult a healthcare professional before starting a pelvic floor exercise regimen.

The EMS Technology

EMS, or Electrical Muscle Stimulation, represents a cutting-edge technology that has revolutionized muscle training and rehabilitation. Essentially, EMS involves using electrical impulses to stimulate muscle contractions, replicating the natural signals sent by the central nervous system during physical activity. This technology has diverse applications in fitness, sports training, and physical therapy.

EMS devices typically include electrodes placed on the skin over targeted muscle groups, delivering controlled electrical pulses to induce muscle contractions. This not only aids in muscle strengthening but also enhances endurance and accelerates recovery. EMS technology has proven particularly beneficial for individuals with limited mobility, athletes focusing on targeted muscle development, and those undergoing rehabilitation.

The versatility and effectiveness of EMS make it a valuable tool for optimizing physical performance and promoting overall muscle health.

YoniFlex EMS Kegel Trainers

YoniFlex offers a range of kegel trainers for both men & women, designed to automatically strengthen your pelvic floor muscles using EMS (Electrical Muscle Stimulation) technology. This innovative approach sets YoniFlex apart from traditional Kegel exercises, providing an effective and easy way to improve pelvic floor health.

How Kegel Muscles are Stimulated via Yonflex Kegel Trainers?

There are two ways the Yoniflex kegel trainer is used to stimulate the pelvic floor muscle. The Pelvic Pads, and Vaginal or Rectal Probes. Let’s deep dive into how each of those works.

Vaginal and Rectal Probes

Vaginal and rectal probes are specialized components used in EMS kegel trainers for more targeted and focused muscle stimulation. Here's a closer look at these probes and their role in pelvic floor training:

Vaginal Probes


Vaginal probes are designed to be inserted into the vagina. They typically have a streamlined and ergonomic shape for comfort during use. The most popular probe available at Yoniflex is the Ada probe, and it is included in the Yoniflex Pelvic Floor Trainer package. Other options include Amelia, Marie, and Nora probes available separately. 


These probes are specifically engineered to target the pelvic floor muscles in the vaginal area. They deliver electrical impulses directly to these muscles, promoting contractions and strengthening over time.


Vaginal probes are commonly used by women seeking to address issues such as pelvic floor weakness, urinary incontinence, or for general pelvic floor strengthening. They are often recommended for postpartum recovery and women experiencing challenges related to childbirth or age.

Rectal Probes


Rectal probes are intended for insertion into the rectum. They are shaped to facilitate ease of use and comfort during the training session. The most popular rectal probe available at Yoniflex is the Cleo probe, and it is included in the package 


Rectal probes target the pelvic floor muscles in the rectal area. The electrical impulses generated by these probes stimulate contractions in the muscles, aiding in strengthening and toning.


Rectal probes are commonly used for individuals, regardless of gender, who may benefit from focusing on the pelvic floor muscles in the rectal region. This can include individuals dealing with conditions such as fecal incontinence or those looking to enhance overall pelvic floor health.

Adjustable Intensity and Programs

Similar to external electrode placements, these probes often come with adjustable intensity levels and programmed workouts. Users can tailor the intensity to their comfort level and gradually progress as needed.

Hygiene and Cleaning

Given the nature of internal use, these probes are designed with hygiene in mind. They are made of medical-grade materials that are easy to clean and sanitize after each use.

Additionally, consulting with a healthcare professional before starting any pelvic floor training regimen is advisable for individuals with specific health concerns or conditions.

Pelvic Pads

Pelvic pads, often referred to as electrode pads or stimulation pads, are components used in pelvic floor trainers aka kegel trainers that operate on Electrical Muscle Stimulation (EMS) technology. These pads play a crucial role in delivering controlled electrical impulses to stimulate the pelvic floor muscles. Here's an overview of pelvic pads and their function.


Pelvic pads are typically small, adhesive pads that adhere to the skin surface in the pelvic region.

They are connected to the main unit of the Yoniflex kegel trainers via wires.


These pads are strategically placed on the skin over targeted pelvic floor muscles. The placement may vary depending on the specific training goals and the design of the trainer device.

Electrode Function

The pelvic pads function as electrodes, conducting electrical impulses from the device to the underlying muscles.

When the EMS kegel training device is activated, the pelvic pads transmit controlled electrical stimulation to the pelvic floor muscles, causing them to contract and relax.

Muscle Stimulation

The primary purpose of pelvic pads is to induce muscle contractions in the pelvic floor region. This stimulation mimics the natural signals sent by the central nervous system during physical activity.

The repeated contraction and relaxation of the pelvic floor muscles contribute to strengthening and toning over time.

Adjustable Intensity

Yoniflex kegel trainers along with the pelvic pads typically come with adjustable intensity levels. There are 17 adjustable settings to choose from. Users can customize the intensity based on their comfort level and gradually increase it as they progress in their training.

Hygiene and Care

Proper hygiene is essential when using pelvic pads. Users should follow the proper instructions for cleaning and maintaining the pads to ensure effectiveness and prevent skin irritation.


Pelvic pads are designed for use with specific kegel trainers. It's crucial to use the pads provided or recommended by the manufacturer to ensure compatibility and optimal performance.

Pelvic pads, along with vaginal or rectal probes, contribute to the effectiveness of EMS kegel trainers by providing a targeted and controlled approach to pelvic floor muscle training. Users should always follow the instructions provided by Yoniflex for the correct placement and usage of pelvic pads in conjunction with the specific kegel trainer device.
