《Approx. 2.5 times the exercise effect of regular walking*1》Supervised by former marathon Japanese representative Masako Chiba! Multifunctional exercise board "Jog Board" for "fun bouncing at home" newly released | Jogfoot

Zyva Studio Co., Ltd. (Headquarters: Shibuya-ku, Tokyo; Representative Director: Minoru Fukano), a consolidated subsidiary of PAS Inc. (Tokyo Stock Exchange Standard Market, Code 3840), which develops the health equipment brand "Jogfoot," born from the desire for everyone to walk healthily on their own legs forever, has released the "Jogfoot Jog Board" (19,800 yen including tax) on July 3, 2026, developed under the supervision of former marathon Japanese representative Masako Chiba.

This product is a renewal of Jogfoot's popular fitness gear "Jog foot," which has surpassed a cumulative total of 168,000 units shipped (June 2021 - May 2026). It is a new form of fitness gear that allows users to efficiently train muscles and joints while reducing the burden on their legs and hips simply by stepping or lightly jumping. It features a special 3-layer structure with excellent resilience and shock absorption, allowing the entire family, from children to seniors, to use it at home by "just having fun, light bouncing."

Development Background: For a 100-year lifespan, walking on your own legs forever

"In a 100-year lifespan, it is important to use your muscles and move your joints with a reasonable load every day in order to walk healthily forever."

These are the words of Masako Chiba, a legend in Japanese women's long-distance running, who was the first in the world to win medals in both track and marathon events at the World Athletics Championships.

Running or walking outdoors can be a concern for the burden placed on the legs and hips, especially the knees.

It was the desire of an athlete who has experienced tough training to "want anyone to train easily at home and have fun without putting a strain on the joints of their legs and hips" that led to the development of this product.

We propose a new "Masako Chiba Running Method" that can be continued safely at home, regardless of the weather.

Product Features

1. 【Amazing Exercise Effect】Approx. 2.5 times the exercise effect of regular walking*1

Simply by stepping on the "Jog Board," you can efficiently train large muscles, with the rectus abdominis increasing by approximately 165% and the rectus femoris by approximately 152%*2. Furthermore, respiratory metabolism (calories burned) also increases by approximately 185%*3, allowing for effective aerobic exercise in a short period.

2. 【Joint-Friendly 3-Layer Structure】Shock absorption & resilience reduce landing impact by about half*2

To minimize the burden on the ankles, knees, and hips, a special 3-layer structure is adopted: a "soft high-resilience mat," a "flexible and durable main board," and " urethane springs that absorb shock." This reduces the impact of landing by approximately 45% compared to normal jumping. The exquisite resilience allows you to bounce up with little effort, reproducing the feeling of stepping when running. It also absorbs shock, making it quieter and allowing use at any time in apartments and other residences.

*The mat has been renewed to a high-resilience material that is resistant to wrinkles and dents.

3. 【Infinite Ways to Use】2-way specification by changing springs

In addition to jogging, jumping, and stepping exercises, by removing the springs, you can freely arrange exercises such as yoga, planks, stretching, and hip/ankle movements in a 2-way specification. The wide stepping surface (60x50cm) and stable low-profile design (height 14cm) make it ideal for balance muscle training to prevent falls.

4. 【Compact Storage】Only 8cm thick when springs are removed

No troublesome assembly required; simply attach the springs to start using immediately. After use, remove the springs and it becomes only 8cm thick, allowing for neat storage without taking up space, such as in gaps between furniture or under sofas. It is also lightweight at approximately 4kg, making it easy to move between rooms.
