A BIG difference

Hi Andy.

I just wanted to tell you that I really enjoyed our climbing session. It was a great moment of sharing and I learned a lot. You really are good at transmitting and explaining. Am applying the 4 advices that I memorized (feet placement, using the legs as they are much stronger than the arms, positioning the center of gravity and finding resting slots while climbing).  I can see a BIG difference.

So thank you!
