When deadlifting, it is advised to keep the bar as close to your body as possible because it is easier to maintain tightness in your lats, upper back, and core this way. However, when doing this, you often see the bar scraping against the shin, causing bruising and even bleeding. So, a way to prevent this is to wear shin guards or deadlift sleeves. That way, you can keep that bar path close, your body tight, and avoid the extra pain.
