Performing the: A Step-by-Step Tutorial Assisted Lying Hamstring Stretch
Bend one knee and keep your foot flat on the ground, while extending your other leg straight up into the air.
Use a resistance band, towel, or similar object, loop it around the foot of your extended leg, holding onto each end with your hands.
Gently pull on the band or towel to guide your straight leg towards your chest, stretching your hamstring. Ensure you keep your leg straight and your foot flexed.
Hold this position for 20-30 seconds, then slowly release and switch legs to repeat the stretch on the other side.
