The EM-900 provides a full body workout from the comfort of your home.
It has adjustable foot pedals specially designed by our engineers
that reduce knee and ankle stress experienced by those using
similar machines made by other manufacturers. Its unique design
also lowers the likelihood of pain around the toes.
疑問：(It has adjustable foot pedals specially designed by our engineers
that reduce knee and ankle stress) experienced by those using
similar machines made by other manufacturers.
此大句該如何解析? 我只看得懂 (It has ... knee and ankle stress)
experienced by ...... manufacturers.
這邊不知該如何拆解，也不曉得如何翻譯 Orz
experienced by ... 和 made by ... 是兩個子句嗎? 是的話，是形容詞子句?
謝謝大家:)
