In rock climbing, safety equipment (such as safety buckles, ropes, etc.) is a key means to prevent falling and protect life and safety. **It is strongly recommended not to use protective equipment such as safety buckles under any circumstances. This is the basic requirement to be responsible for the safety of one's own and others' lives. If you are discussing unprotected free Solo rock climbing, you need to be clear: **This is an extremely dangerous behavior. Only a very small number of strictly trained professionals try it under specific conditions. Ordinary people should never imitate it. Even so, unarmed rock climbers still rely on the following principles to minimize risk (but the risk is still extremely high)： --- ### **1. Strict control at the technical level** -**100% reliable climbing ability**: Only try to climb routes that are far below the limit of your own ability to ensure that every action does not need to be forced. -**Route familiarity**: You must know every detail of the route (fulcrum, friction, rock condition) well, and you usually need to practice with protection multiple times before trying. -**Movement accuracy**: Avoid dynamic jumps or irreversible movements, and always maintain three-point contact (two hands and one foot or two feet and one hand are stable). ### **2. Physical and psychological conditions** -**Physical reserve**: Strong finger strength, core stability and endurance to ensure that fatigue will not lead to mistakes. -**Absolute focus**: Eliminate all distractions (such as mood swings, external noise), and your psychological tolerance needs to be extremely strong. -**Risk assessment**: Judge environmental changes (such as rock humidity and temperature) in real time, and be ready to give up at any time. ### **3. Environmental selection** -**Rock type**: Give priority to rocks with high friction (such as granite) to avoid fragile or slippery rock walls. -**Height control**: The lower the risk, the smaller the risk, but even falling from a low place can be fatal (such as loss of body posture). --- ###**Emphasize again** -**The mortality rate of unprotected rock climbing is extremely high. Even experienced rock climbers often die due to minor mistakes (as shown in Alex Honnold's "Free Solo" documentary). -**Alternative **: If you want to challenge yourself, you can choose bouldering (low altitude + crash pad protection) or top rope rock climbing instead of giving up safety equipment. There is only one life, and the fun of rock climbing should be based on safety. Please always use professional equipment and receive formal training!
