疫情的緣故，選擇在家健身的人變多 了，然而在家健身的設備沒有健身房來得多元，以及重量重調整不易，攜帶不便，甚至要是發生運動失誤，有可能造成嚴重的損傷。
因此以彈力繩的使用作為發想，透過電磁的原理，取代原本無法調整的阻力，使其可以隨時隨地的使用。
Due to the Covid-19, more and more people choose to exercise at home. However, the equipment for exercise at home is not as diverse as that in gyms. Besides, it is not easy to adjust the weight, and it is inconvenient to carry.
Therefore, the use of elastic rope as the idea, through the principle of electromagnetic, instead of the original can not adjust the resistance, so that it can be used anytime and anywhere.
以彈力繩的使用作為發想，透過電磁的原理取代原本無法調整的阻力，藉由改變電流控制磁場進而調整阻力，達到可以隨時隨地使用的目標。
Thank you for your time.
