Instruction :
When I ski my legs form an A-frame shape and it doesn't look very nice, how can I fix this?

Response:
A-frame can occur due to many reasons, this includes improper boot setup, for example, the cuff alignment is incorrect, or technique issues. It is best to consult an experienced boot fitter to ensure the boot is set up correctly. Once you've ensured the boot is set up correctly, it is likely a technique issue. A common cause of A-frame is a result of rotating the outside knee inside more than the inside knee, and this can happen due to wider skis or wanting to create a bigger edge angle. Ideally, we should avoid over-rotating the knee inside as this creates a weaker position and instead rely on moving the hip and upper body into the inside of the turn to create a bigger edge angle and try to keep the outside leg relatively straight.

A good exercise to practice this is the T-drill, where you try to make sure your outside leg is as straight as possible and create edge angle by leaning your whole body into the turn, you'll need to shorten your inside leg by bringing your need to your chest, which will then still allow you to balance mostly on your straight downhill leg.
