How much should you bench if you wheight 250 pounds?

you should be able to lift atleast 50- 100 pouns more than your bodyweight. Depending on your size, body build, and the length of your arms, and your age. For example im 18 years old, i weigh 240 im 6 ft 2 inches and i bench press 310. It al depends on how you lift and what your diet is like.
