I'm at the editing stage (well, and also 2 chapters to finalise) and I have a crucial scene where the hero is holding up a beam and part of the ceiling for about ten-twelve minutes so his friend isn't crushed. Question is, would it be possible to hold up about 500 pounds for that long without doing yourself an injury do you think? It's not like doing a quick snatch. (He's a gent but has spent a lot of time in his youth helping out in the warehouse so he's nice and hunky). My sport was running, I know next to nothing about weightlifting.
