Peace, mercy, and blessings of God be upon you.. I have an Olympia treadmill that was purchased approximately two years ago for 3000 SAR.. It is very clean and has been used only a very few times. For sale and open to offers.. From the control panel, the following features can be observed: ​Diverse programs: It contains 6 pre-set programs (P1-P6) that automatically control speed and incline. ​Speed shortcuts: There are quick buttons for speeds (3, 5, 8, 10 km/h), making it easy to control while running. ​Heart rate measurement: It supports pulse measurement (via the sensors usually located in the handles) to monitor your physical exertion. ​Safety key: The yellow circle in the middle is the location of the "safety key", which is very necessary for operating the device and protecting you in case of a fall, God forbid.
