Since you can adjust the load, you can use it freely from intense training to stretching. It improves blood circulation in your arms in a short amount of time, so it's also useful as a warm-up exercise before playing sports or playing a musical instrument. It is effective not only for sports such as golf, baseball, tennis, badminton, kendo, bouldering, table tennis, and bowling, but also for playing musical instruments such as the guitar, trumpet, and piano. [Professional specification with a sense of weight] Made of aluminum alloy, it has an athlete specification in both weight and strength! It has received high praise because it is heavier than plastic and can handle more stress. [Load equivalent to 60 kg of dumbbells] The higher the rotation speed, the more force you need to apply, so you can adjust the load depending on the scene. You can freely control the strength, with low speed rotation equivalent to 10 kg of dumbbells and high speed rotation equivalent to 60 kg. [Small and quiet for training anytime, anywhere] The size is about the size of a baseball, so it's easy to carry. Because it rotates quietly and smoothly, you can train anywhere, whether at home, at work, on a trip, on an expedition, or on a business trip. It doesn't take up space like heavy dumbbells or barbells, so you can train efficiently in a space-saving manner.
