This is a YIJIAN brand treadmill. Enjoy music while you work out with the built-in USB port, MP3 input (Aux), and speakers. Save space with the hydraulic folding system. Reach your fitness goals with P1 to P12 pre-set programs for weight loss, stamina, and hiking. Track your progress easily with the central display showing speed, time, distance, and calories. It is the perfect all-in-one home gym solution. Used very little; purchased three years ago but used for less than a year.
