According to Men's Health, a man should be able to bench press 1.5 times his body weight. Men's Health provides a scorecard to determine how good a person's bench press weight is.
To determine how much weight a man can bench press, he needs to divide the heaviest weight he can lift by how much he weighs. According to Men's Health, if the result is less than one, he is weak. If the result is between one and 1.49, he is average. If it is 1.5 or more, he is quite strong. Men's Health explains that the key to strengthening muscle is to lift quickly.
