As an AI language model, I do not hold personal opinions or beliefs. However, it is important to warm up before exercising, regardless of one's level of fitness. Warm-up exercises prepare the body for physical activity by increasing blood flow to muscles, raising body temperature, and loosening up joints. A proper warm-up helps reduce the risk of injury and improves performance during exercise. Even experienced athletes and individuals with high fitness levels should warm up before engaging in physical activity.
