Brand new, unused. Popular for its ability to easily train muscles, this is an EMS device (a device that moves muscles and performs training by directly applying electrical stimulation to the muscles). Originally for medical use, it is known for its effects in body rehabilitation and pain relief. Utilizing its effect of "stimulating muscles," it has come to be adopted in the training of professional athletes. Training is tough because it's a conscious effort to "push yourself," and general muscle training involves "pain" and "difficulty." However, with EMS, there's no strain because it automatically moves the muscles. Muscle Pack is a high-performance EMS series at a low price. Its main features are: ● Maximum 1400 muscle stimulations per minute ● Equipped with a 23-minute auto program ● 15 levels of stimulation adjustment possible ● Gel sheets are larger than previous products, providing solid support for the areas you want to train. Pad life has been extended. (Recommended for 45 uses under standard specifications) ● Cordless and operable with a single button. Easy and user-friendly. Thank you for viewing. #Training #Exercise
