Sitting tilt
In this option, for comfortable stretching, you can use loops or a towel that winds up behind the feet. If the flexibility of the muscles is high, then you can grab your feet or lower leg with your hands. To perform the tilt, you need to take a sitting position on the floor, straightening both legs in front of you, then tilt your torso forward and, with the help of your hands, stretch the spine forward, as if lengthening it to the feet. Do not try to lie on your hips, it is important to stretch your back, not your hamstrings.
