A bog-standard quadriceps stretch. With pointers on how to avoid certain mistakes. Hold for 20 seconds on each sides. This stretch should be felt at the front of the thigh or hip. If it causes lower back pain, or tingling feeling in the leg, or if you feel the stretch in the lower leg or foot, please do get in touch as this may need to be tweaked for you. Make sure to hold onto something while doing it to avoid falls.
