Cool, please do.
I have some rock-climbing friends and one is a guy who always arm wrestles me. He's non-vegan and we tease each other a bit. We've tied a few times and I won all the other times.
He has climbing holds in his house and he challenged me to a pull-up contest. I thought he'd win because of his grip strength and general arm and back and technique strength, but I beat him again.
Now he wears around a Vegan Bodybuilding & Fitness t-shirt and supports our lifestyle
He was even a guy who was in the audience as we previewed our movie Vegan Fitness - Built Naturally and helped give feedback before we released it a couple weeks ago.
I hope to get back into climbing again, it was so much fun, and great to get over that fear. I was so scared I couldn't speak or move for quite a while, but so much fun too!
