How to Prevent Bicep Tears During Heavy Rows and Deadlifts

I saw a video of someone tearing their bicep while doing a heavy deadlift with a mixed grip and it absolutely terrified me. I am looking for how to prevent bicep tears during heavy rows and deadlifts. I currently use a mixed grip for my heavy sets and I am wondering if I should switch to a hook grip or use straps instead.

I have also heard that keeping the arms completely straight during the pull is key. I sometimes catch myself trying to curl the weight up a bit when it gets heavy. I am also trying to be careful with my heavy barbell rows because I feel a lot of strain on the bicep tendon at the bottom of the movement.

Do you guys have any safety tips for protecting the biceps during these big compound movements? I am considering using some compression sleeves or just being more conservative with my weight jumps. I want to get strong but a bicep tear sounds like a nightmare that I want to avoid at all costs!
