Performing the: A Step-by-Step Tutorial Hamstrings Lying Stretch
Lift one leg off the ground while keeping the other leg flat on the ground, and hold onto the back of your thigh with both hands.
Slowly straighten your knee as much as you can, while keeping your foot pointed towards the ceiling, until you feel a gentle stretch in your hamstring.
Hold this position for about 15 to 30 seconds, taking deep breaths to help your muscle relax and stretch.
Lower your leg back to the ground, rest for a moment, and then repeat the stretch with the other leg.
