About this product: ● This is an abdominal roller that allows you to perform本格的な筋力トレーニング (authentic strength training) at home. The simple movement of extending and contracting with both elbows on the main unit and knees on the floor makes it easy for people of all ages to try. You can naturally maintain a plank position, allowing you to train various areas such as the abdominal muscles, pectoral muscles, latissimus dorsi, biceps, biceps femoris, and gluteal muscles with just one unit. ● The abdominal roller can be used at different levels, from beginner to intermediate to advanced, depending on your posture, extension distance, incline, and weight distribution, making it also recommended for advanced trainers. With an abdominal roller at home, you can start training at any time without worrying about your clothes. This is the perfect training equipment for those who have been pointed out during a health checkup, want to review their current diet, want to save time and money on going to the gym, or are looking for a workout they can do alone. ● The abdominal roller has two thick wheels vertically, providing more stability than it looks, preventing deviation to either side. The wheels are equipped with an auto-return function, so even beginners who are not yet used to the exercise or haven't built up enough strength to return on their own can smoothly return from a difficult position. Furthermore, the handle tip is equipped with a timer, which increases exercise efficiency by setting goals for your training. ● A knee mat is also included in the set to protect your knees during training. The surface is textured with a bumpy design, providing excellent stability and a non-slip function. Furthermore, the thick design makes it difficult to feel the impact on the floor even when applying force, and it is designed to reduce the burden even when training with your knees on the floor. ※ 【Set Contents】 Abdominal roller x 1, Timer x 1, Knee mat x 1 【Size (approx.)】 Abdominal roller: 45cm x 37cm x 22cm 【Color】 Abdominal roller: Black, White ※ You can choose your favorite color.
