Answer
Hello,

  Well, first you must know that a defensive lineman must have a low sense-of-gravity. You must be able to fire out without lifting up. Learn how to engage with a lineman and get rid of him quickly. Good explosion from the lower body. Squats, broad jumps and bear crawls will help with that explosion.

  Never let a lineman get in your chest or in the center of your body, because if he does it is to easy for him to block you.
