A. Avoid slipping
B. Reduce fatigue
C. Increase stability
D. Increase speed
🧠 Explanation:
When a person climbs uphill, they naturally bend forward to maintain their balance. By leaning ahead, the body’s center of gravity stays aligned over the feet, reducing the risk of falling backward. This posture helps distribute body weight more effectively against the slope. The forward bend also lowers the center of mass, which enhances stability. This principle is a basic concept in physics related to equilibrium and is commonly applied in sports, trekking, and mountaineering.
