Climbing problems, often referred to as "bouldering problems," are specific routes or challenges that climbers attempt to solve on rock walls or boulders. Each problem has a unique set of holds and movements that require strength, technique, and strategy. Climbers assess the best way to navigate these routes, often using their hands and feet to grip various types of holds, like edges and slopers. These problems are usually graded based on their difficulty, helping climbers choose challenges that match their skill level. Popular grading systems, such as the V-scale in the United States, categorize problems from easy to extremely hard. Climbers often gather in groups to share tips and encourage each other as they tackle these exciting challenges.
