The generator kicks in only during the swing phase of a footstep when the muscles are already braking, so it doesn’t take power away from your step and slow you down.
发电机的开启只在肌肉已经开始阻止摆腿的阶段。 他不用夺走你走路的量使你慢下来。

With every step you take on a treadmill and with every bicep curl, you turn surplus calories into motion that could drive a generator and produce electricity.
你所走的每一步都是在脚踏车上with every bicep cur，你转化剩余的卡路里为转动，它能驱动一个发电机并产生电力。
