美国采购需求：三头肌绳、阻力带手柄、人体工学哑铃、地雷、附件、杠铃地雷球

I recently purchased one of your steppers and have been using it regularly for a few months. Unfortunately, I encountered a significant issue when both cables broke during use. This has not only been disappointing but also quite concerning for my safety. I would like to know what solutions or assistance you can provide regarding this matter. I'm looking forward to your prompt response and hope we can sort this out quickly. Thanks for your attention!
