Stretching can prevent injuries during workouts by improving flexibility and enhancing the range of motion in muscles and joints. A comprehensive stretching routine prepares the body for physical activity, reducing muscle tightness and enhancing circulation. Proper warm-up stretches increase blood flow to the muscles, decreasing the risk of strains and sprains. Additionally, post-workout stretching aids in muscle recovery by helping to reduce soreness and stiffness. Incorporating both dynamic and static stretching can be beneficial for overall injury prevention in fitness routines.
