Lie on your side with your body straight and legs stacked. Bend the top knee and reach back to grasp your ankle or foot with your hand. Gently pull the heel toward your glutes until you feel a stretch along the front of the thigh. Hold the stretch with steady breathing for 20–30 seconds, then switch sides.
Log your quadriceps lying stretch sets in 1RM.fit and watch your estimated 1RM update automatically as you get stronger.
