A muscle stretching machine designed to provide the user with easy system of functional stretching and also provide the user with flexibility feedback information as to the performance of the stretch, such as but not limited to the angles of the stretch, the force of the stretch, the position of the stretch, and the duration of the stretch. A user of the muscle stretching machine can turn on the central processor, adjust the height of the machine to suit their height or to suit the type of stretch to be performed, step onto a round turntable subassembly, place the leg to be stretched on a foam pad designed to raise and lower the leg, pull down on a handle to raise the leg being stretched and read the information displayed on the central processor. When the handles are pulled down the leg is raised. When the handles are allowed to go up the leg is lowered. When the leg is raised and lowered the displays on the control panel change in real time showing the raised or lowered angle of the leg, the, force required to raise or lower the leg, the amount of twist angle on the leg not being stretched, and the height of the pivot point of the stretch.
