Cliff-hanger

I don’t look like rock-climbing material. I’m only moderately athletic, I don’t love heights, and I can do exactly one push-up. But now that I’ve learned the basics of the sport, I know that my noodle arms are not reasons to stay away from rock faces. As Mykael Lazzeri, an instructor at Mission Cliffs climbing gym in San Francisco, says: “If you can climb a ladder, you can climb a rock.”

This is good news for anyone looking for an outdoor activity that is both physically challenging and mentally engaging. Steve Gerberding, an instructor at Joshua Tree Rock Climbing School and a 26-year climbing veteran, says, “Rock climbing is puzzle solving.”

THE GEAR
The variety of rock-climbing gear is staggering, but there are only a few items you need to get started. All courses and gyms will rent or lend you gear to use.

• Helmet: Highly recommended for all outdoor climbing. It will protect you if you fall, and also protect you in the much more likely event of falling debris. From $50.
• Chalk bag: Not necessary, but as Steve Gerberding says, “A chalk bag will help you look cool while you’re stalling on the face.” From $12.
• Harness: The rule here is to find one that is comfortable and fits properly. Always try a harness on before purchasing. From $22.
• Locking carabiner and belay device: These pieces of hardware are belaying essentials. From about $15 each.
• Shoes: Rock-climbing shoes are an absolute must and are generally worn very snug. Having your own pair ensures the best fit. From $80.
