PROBLEM

The more you neglect it,

the more your inner thighs and buttocks gradually collapse

[Image: Photo showing a person pinching the inner thigh fat]

Inner Thigh Fat

[Image: Photo showing a person’s buttocks in underwear]

Buttocks Fat

The inner thigh muscle called the adductor muscle holds the pelvis and plays a key role in maintaining lower body balance.

What happens when the adductor muscle that aligns the lower body weakens?

[Image: Anatomical illustration showing the adductor muscles: Adductor longus, Adductor magnus, Adductor brevis, Gracilis]

Fat accumulates on the inner thigh, and the pelvis tilts, causing the buttocks to sag downward and spread outward.

Lower body circulation decreases, making swelling and cellulite easy to develop.

Gradually Sagging Body..

We solve tightness in just 5 minutes a day!

Inner Thigh

Detail 01

For deep muscle exercise, only InnerTie works.

Jjjoim is convenient even at home

How to exercise

Various exercise methods using tightening

Inner muscle exercise | Inner thigh

Exercise to Reduce Belly and Thigh Fat | Hip Bridge

Exercise to Reduce Arm Fat | Biceps Curl

Abdominal / Hip Exercise | Tight Stretch

Kegel Exercise | Detail 02

Concerns you can't express in daily life,

Kegel exercise is the answer.

Kegel Exercise Developed by Obstetricians and Doctors

Kegel Exercise

The muscles located below the pelvis, called the 'pelvic floor muscles', play a role in contracting the area around the pelvis.

Kegel exercise strengthens these pelvic floor muscles, and with consistent exercise, it can help muscles in the pelvic area that have weakened.

Relieve discomfort in daily life caused by tightness.

Final edition high-elasticity compression spring

[Image: Comparison photo showing a thinner 2.5CM spring labeled "Initial product" and a thicker 3.6CM spring labeled "Diet and Jjoimi"]

We achieved the optimal strength necessary for muscle stimulation from the difference in thickness of the 4-coil spring.

FAQ

Frequently Asked Questions

Q. Is there a strength difference depending on the color?

A. Yes, the strength varies depending on the color. For first-time users, we recommend the following order:

(Beginner) Baby Pink

(Intermediate) Wood Beige

* The perceived strength may vary depending on individual muscle strength.

Q. The product is misaligned. Is it defective?

A. Because the sponge connection points differ structurally, slight misalignment naturally occurs. When equal pressure is applied during use, the alignment corrects itself and this does not affect exercise performance.

Q. The sponge is compressed.

A. The sponge may be compressed during manufacturing and shipping. It gradually restores while in use and does not affect exercise function. If it remains uncomfortable after use, please contact customer service.

Q. Can I use it on other areas besides the inner thighs?

A. Yes. It can be used for arms, waist, abdomen, and other whole-body muscle exercises. Instructional exercise videos are also provided.

Q. How do I care for the product?

A. The sponge on the surface is not washable. If soiled, gently wipe with a wet cloth and let it air dry naturally. Exposure to high temperatures or direct sunlight may cause deformation.
