Hi I'm Steve Nichipor. I'm a professional mountain guide with Brenton Wood Ski Resort and I'm going to show you types of rock climbing holes. There are many types of climbing holes depending on the type of rock and difficulty of the climb. Common natural outdoor holes include crimps, jugs, cracks and flakes. Here we'll focus on common indoor climbing holes. Beginner routes usually have large, easy to grip holds commonly referred to as jugs. These holds make it much easier for beginners to hold on and feel secure, allowing them to learn about the other intricacies of climbing movement. Jugs are also the best type of hold for keeping your fingers healthy. More difficult routes will have smaller holds that only allow the fingertips to grip. These are often referred to as crimps. It's important not to overdo it with hard climbs on crimps as your finger tendons can be easily injured, forcing you to take time off from climbing. Slopers are holds that don't let you hold the rock at all so the only way to hold on is with pure friction. These are generally only found on very difficult climbs or used as foot holds. Pockets are holds that only allow you to hold on with a couple of fingers. Pinches are holds that you can squeeze from both sides but can't hold on to the top.
