How much can the average 40-year-old bench press?
It Usealy is 80-100 for 1 rep or 40-60 for 10 reps this is a bad, wrong answer. The average 40 year old male bench presses in the mid-to high 100's, and with proper training, should attain a 250 pound bench press.
It depends on the average male. Some can bench-press more weight than others, depending on their pectoral, biceps and back-muscle strength they have. Some can bench-press as much as 300 lbs; others may only be able to bench-press only around 100 lbs. Just like there are many different body types of each man, there are different levels of strength that each and every individual 21 y.o. man has.
