Sit on floor or mat with legs apart and knees straight.
Reach toward one foot or bring torso toward one leg. Hold stretch for 20 seconds. Repeat with opposite leg.
Alternatively, leg not being stretched can be bent so sole of foot is next to stretched thigh. Keep knee of stretched leg straight by tensing Quadriceps. Knees may inadvertently bend if feet are extended off of thick mat or bench. Spine may be kept straight. Pelvis may be tilted forward to intensify stretch.
