Bend your left knee slightly and hinge forward from your hips until you feel a stretch in the back of your right thigh. Hold the stretch for 30 seconds, then repeat with the left leg.

- Seated hamstring stretch: Sit on the floor with both legs straight out in front of you. Bend your left knee and bring your left foot to your right thigh. Place your right hand on your left thigh and gently push your knee toward the floor. Hold the stretch for 30 seconds, then repeat with the right leg.

- Supine hamstring stretch: Lie on your back with both legs straight out in front of you. Bend your right knee and bring your right foot to your chest. Wrap your arms around your shin and gently pull your knee toward your chest. Hold the stretch for 30 seconds, then repeat with the left leg.
