Seated Knee Flexor Stretch
Description
The seated knee flexor stretch is a seated forward-fold variation where you sit with one leg extended and the other bent (foot against inner thigh), then fold forward over the extended leg. It deeply stretches the hamstrings (knee flexors), calves, and lower back of the extended leg.
