Thank you for viewing! ・Training tubes work out your whole body! You can train your upper body (shoulders, wrists, back muscles) and lower body (glutes, thighs, legs)! ・Not only can you increase your strength and endurance, but you can also easily stretch and improve your flexibility! ・Double structure of latex and fabric! Because of the polyester outer layer, it won't tear and is durable! ・It's the smallest and lightest, and can be put in a storage bag, so you can carry it anywhere, at home or at the gym! ☆Because this is an imported product, there may be some imperfections compared to Japanese products, such as rough stitching, small scratches, loose threads, the smell of packaging materials, and size errors, but we are able to offer it at a low price! If you have any other questions, please feel free to ask (^ ^)
