An essential practice for injury prevention during exercise is implementing a proper warm-up and cool-down routine. Warming up prepares the body by increasing blood flow to the muscles and improving flexibility, while cooling down helps restore heart rate and muscle recovery. Additionally, understanding one's own limits and using appropriate techniques is vital. Engaging in mindful stretching post-exercise and ensuring adequate hydration can also significantly lower the risk of injuries, enhancing safety and overall performance in the fitness regimen.
