Warm-up exercises are physical activities performed before more intense workouts or sports. They help prepare the body by increasing blood flow to the muscles, improving flexibility, and reducing the risk of injury. Common warm-up activities include light jogging, dynamic stretches, and mobility drills. These exercises typically last 5 to 15 minutes and focus on the major muscle groups used during the main activity. By gradually raising the heart rate and loosening the joints, warm-ups enhance overall performance and ensure a safer exercise experience. Incorporating warm-up routines is essential for athletes and fitness enthusiasts alike.
