What is the correct posture for climbing stairs, up and down? There seems to be contradictory advice on the internet. Some advocate keeping the back straight and perpendicular to floor, while others insist that you hinge forward at the hips. The former is very difficult, the latter more 'natural', but what is correct? What should the relative positions of knee and toes be on the forward leg? What posture protects both the knees and the lower back? Its all very confusing. Its very good exercise, but without proper posture can cause knee and lower back strain. Walking up even a fairly steep incline is easier than climbing stairs. So the posture is likely to be crucial, especially regarding the knees.
Advice with some visual cues from real life, the most excellent part of the Gokhale Method, will be greatly appreciated. Just walking up and down normally will be fine. Dont really want to run up and down. But do want to do it in a sustained fashion for 10-15 minutes at a time.
