In rock climbing, in order to maximize safety and reduce the risk of falling, it is generally strongly recommended to use protective measures such as carabiners. However, if carabiners cannot be used in certain situations, you can consider the following tips to minimize falls: 1. **Choose a suitable route**: Choose a route with lower difficulty, smaller inclination, and shorter descent distance, so that even if you fall, the risk is relatively small. 2. **Good physical preparation**: Strengthen core muscle groups, upper limb strength and endurance training to improve your physical fitness and make your movements more stable. 3. **Plan the route**: Before climbing, carefully observe the climbing route to find out where you can stay safely and the key grip points. 4. **Control the rhythm**: Maintain a constant speed and rhythm, avoid unnecessary fast movements and throwing movements to reduce physical exertion and the chance of mistakes. 5. **Use the "three-point support method"**: Always keep at least three parts of the body (two hands and one foot or two feet and one hand) firmly in contact with the rock surface to improve the body's balance and support. 6. **Pay attention to balance**: Keep the center of gravity of the body close to the rock wall, reduce the swing of the body, and ensure greater stability and safety. 7. **Use friction correctly**: Be good at using the friction of the feet to reduce the weight on the upper limbs, especially when climbing vertical surfaces and slightly inclined positions. 8. **Stay calm**: When encountering difficulties and tension, stay calm and try to avoid being impatient and panic, so as to better judge and respond to the next action. 9. **Understand and use environmental characteristics**: Use the natural grooves, cracks and protrusions on the rock wall for support and climbing. Even so, rock climbing still has potential dangers. It is recommended to wear necessary safety equipment in any case and train and practice under the guidance of professionals.
