Just grip it and shake it. A "sustainable" weight cushion made from recycled fishing nets.
"Ami Fit" is a weight cushion that allows you to incorporate exercise into your daily life simply by gripping and shaking it. Developed under the supervision of diet trainer and mental coach Keisuke Koyama, it aims to reduce the "heaviness of the first step" that many people experience when they feel they should exercise but find themselves hesitant in front of equipment. The weight is set between 1.0kg and 1.5kg, making it easy for beginners to pick up while still effectively engaging the body. Its soft cushion shape eliminates the intimidating feel of dumbbells, allowing it to serve as interior decor around your sofa or desk when not in use, and as a weight when you want to exercise—this "dual-use" design eliminates the hassle of retrieving equipment, enabling you to naturally incorporate exercise into the gaps of your daily life. The inner material is made from "REAMIDE," a recycled nylon supplied by Refineverse Group. This material is made from used fishing nets and has a lower CO2 emission compared to virgin materials. Each movement for health contributes to reducing environmental impact—this product aims to embody such a cycle.
