A dyno is an explosive “dynamic” move that normally involves jumping from one hold to another. Dyno’s can be tricky to stick but are great fun. Often seen in Hollywood movies as they look cool, dyno’s are the ultimate “win it or bin it” move in climbing. If you get it right, it feels great, if you get it wrong, you’re falling. Many climbing exhibitions have a “dyno contest”, where the climber who manages to make the furthest hold wins. These always tend to be crowd pleasers and are worth a watch if you get the chance.
