What I mean is, if I weight 215 lbs, with a somewhat muscular build, and I’m doing regular straight backed push-ups, how much of that weight am I lifting? I know it’s a lever problem, but I don’t know how to solve it with the differing weight distributions. Obviously the apparent weight is less if all the weight is in your feet, but most of my weight is in my upper body (chest, back, arms), and a decent amount in upper legs. So, are my pushups the equivalent of benching 115 lbs? 80lbs? 150 lbs? I can’t really go by feel, but I can do 60 pushups in good form in 2 minutes, and I know I can’t bench 135 lbs 60 times in 2 minutes, so it’s got to be less than that, but by how much?
(and yeah, I know they’re not identical exercises, since pushups use the abdominals a decent amount, but I’m concentrating on the chest/triceps lifting action here)
