G-String Pro Training Bouldering Climbing

This is the G-string Pro.
I only hung on it about 3 times for climbing training. It has been stored in a dark place ever since.
There are signs of use, but they are mostly from rubbing during storage and transport.

Retail price: ¥19,930
Very limited availability in Japan. This is a popular item that sells out quickly, making it very difficult to obtain.

This is an innovative system that allows you to simultaneously correct your form for 18 different grip types and strengthen your core with TRX. The Gstring can be quickly changed for crimps, jugs, slopers, and more, and is designed to strengthen all the grips necessary for climbing. Furthermore, it features a special friction structure that eliminates the need for chalk, making it safe for indoor use. While hanging training equipment like Rock Rings (Metolius) and La Sportiva (Lapis) are well-known, they lack grip adjustability, leading to repetitive training and an overemphasis on chest muscles, which can hinder overall movement. Unlike fixed simulators, the Gstring's hanging design allows for angle changes, enabling training with adjusted body angles.
