Alex Honnold answers questions from Twitter about why yellow holds suck, how to jam cracks, how to fall comfortably and much more. Honnold, arguably the best free-soloist of all time, has been in the media spotlight for years thanks to his bold free-solos of big walls, which are often caught on camera.

Honnold’s mom, Dierdre Wolownick, recently wrote a book called The Sharp End of Life: A Mother’s Story. For an interview with Wolownick about her memoir, be sure to pick up the current August/September issue of Gripped magazine.

Honnold will be featured in the upcoming Reel Rock 14 for his speed record ascent of The Nose with Tommy Caldwell.
