Its flexible, ergonomic design adjusts to waist sizes from 75 to 130 cm, and the removable LCD control unit offers 5 pre-programmed training sessions with adjustable intensity, giving users a straightforward way to fit muscle training into their day.

- The countdown timer shows the remaining session time; the belt will switch off automatically at the end of the program.

Frequently Asked Questions
Can the EM 39 be used by people with a pacemaker?
No. Beurer states this device must not be used by people with a cardiac pacemaker or other implanted electronic device. It should also be avoided during pregnancy or by people with epilepsy or cardiac arrhythmias. If you have any other pre-existing heart, muscle, or nerve condition, consult a doctor before use.
Do I need gel pads or replacement electrodes?
No, the EM 39 uses 4 wear-free water contact electrodes (2 for the abdomen, 2 for the back), so no gel or replacement electrodes are needed. Simply moisten the electrodes with water before each session for good skin contact, which keeps ongoing costs down compared to belts that rely on adhesive gel pads.
What waist sizes does the belt fit?
The belt is flexible and adjustable for waist circumferences from 75 cm to 130 cm, thanks to its ergonomic, extendable design. This range is intended to accommodate most adult body types without needing a separate size variant.
How long do the training programs last?
The EM 39 offers 5 pre-programmed sessions ranging from 22 to 31 minutes, each with independently adjustable intensity so you can find a level that feels effective but comfortable. A countdown timer on the LCD display shows the remaining time for the active session.
What’s the difference between the EM 39 and the EM 37?
The EM 37 is an abdominal toning belt that stimulates only the central and lateral abdominal muscles. The EM 39 is a 2-in-1 belt that adds a second pair of electrodes for the lower back, so it stimulates both the abdominal muscles and the lower back muscles in one session. If your focus is core training alone, the EM 37 is the simpler option; if you also want lower back support and regeneration, the EM 39’s 2-in-1 design covers both areas.
