Is there a difference by developing strength with a bodyweight of 140 pounds comparing to lets say 250 pounds? ,does the strength increase faster on 250 pounds? or its relative the same (i mean ,the only difference is that your pounds help you get stronger but only becuz of your bodyweight not the strength coming from your muscle fibers)
Basically, the bigger you are, the stronger you have the potential to be. That doesn’t mean you necessarily gain strength faster, but your gains will be more consistent/last longer as a newbie than a smaller guys might.
I like to think of strength/size this way: Imagine a guy pushing a car up a hill. That guy represents your muscle fibers. Now, one way to make moving that car easier is to train that one guy so he gets crazy strong. Then, he can push the car with ease. Another way to move that car more easily is to get 3 guys to push the car instead of 1. That would also make moving the car easier. However, the way to make moving the car the EASIEST would be to get 3 guys, and train all of them so they are crazy strong. Then, the car would move the fastest and easiest.
Strength training is the same way. You can stay small (140 was your example) and just train to that your muscle fibers are crazy strong at that size. Or, you can work to add size (250) and because of your mass and number of muscle fibers, you will be stronger. But the way to be strongest is to add size AND focus on training strength. If you can get bigger muscle fibers, and more muscle fibers, and train your body to fire those fibers efficiently, you will be stronger than if you had less muscle OR didn’t train specifically for strength.
That’s a pretty basic answer, but maybe it gets at what your question was asking
I think a lot of strength standards are pretty much the same for people of similar composition and limb lengths. therefore, I think two beginners could make the same jump from, say, a BW deadlift to a 2X BW deadlift in about the same amount of time. But a 140 lb person would add 140 lbs to his deadlift while a 250lb person would add 250lbs to his deadlift in that time frame, so the heavier person would actually progress faster.
I guess what I’m trying to say is average people can increase their strength by steady percentages of their bodyweight which will amount to larger jumps in poundages for heavier people
Answering this question in it’s current form would almost certainly be 100% speculation and conjecture therefore, this question is impossible to answer.
I could have a very lean 140# man in his prime who would blow the wheels off an older, fat, 250# man or I could have a lean 250# dude who would decimate a fat 140# guy.
Now if the scenario is an average build 140# and 250# guy of comparable age, and equal desire to kick ass, I’d speculate that the 250# guy would do better. The human body is a machine and like most machines, the bigger they are the higher the capacity is for work.
Each sport has it’s optimum build. In cycling 155-175# guys dominate. In strongman the big guys excel. This is why many sports have weight classes.
