I purchased this on Amazon, but due to circumstances, I no longer need it and would like to sell it. Material: Polyurethane Brand: JON TORUDO Color: Black Model Name: coshistrech Manufacturer: JON TORUDO 【Valley-Shaped Ergonomic Design】 The biggest differentiating point as an iliopsoas muscle stretching device is this U-shaped curve. With an angle and depth that faithfully reproduces the elbow pressure of a therapist, it directly approaches the deep layers of the iliopsoas and psoas major muscles. It can release fascia adhesions that are difficult to reach with a flat roller, and by continuing training, the range of motion of the hip joint expands by an average of 15-20%. Just using it before stretching also improves training efficiency. 【Hard ABS Core】 With a load capacity of 150 kg due to the ABS integrated molding, it does not warp even with long-term use, and the pressure is evenly transmitted. There is no need to worry about wear and tear like a foam roller, and the hardness does not decrease, reducing replacement costs even if incorporated into a daily routine. Because the surface is processed to be smooth, you can relax comfortably whether you wear clothes or have bare skin. 【Full Body Massage】 This one device can care for multiple areas such as the lower back, back, hamstrings, and calves. By combining sliding and point pressing, you can perform stretching and fascia release simultaneously. From cooling down after running to a short break during desk work, it achieves "relaxation + conditioning" with one device. 【Compact Design for Use Anywhere】 Approximately 28 cm wide and weighing only 500 g. Stretch immediately without choosing a place—an office chair, a gym mat, or a bedside at home. It doesn't take up much space in a bag, and you can warm up before training even when traveling or on business trips. 【Universal Specification Regardless of Age or Physique】 You can finely adjust the pressure just by changing the angle and putting your weight on it, so it can be widely used from beginners to athletes and the elderly. This one device can cover self-care for the whole family and is supported as a cost-effective stretching device.
