dude why cant you just post a picture now? We can easily tell if you have a legit 250 pounds of muscle on you regardless of how fat you are....you said 250 8%....now your 12%bf? You'd be 270 at least....a 270 lb 15% bf dude would still be massive.
Hard to post a picture of the truth when lying......
Humans will always exaggarate their claims to a certain degree they are moraly comfortable with. You always have to keep that in mind whenever someone brings up their so called stats whether its their height, weight, income etc... (This is especially important to keep in mind on dating sites, as most people always will add some inches to their heights, dollars to their income, and substract pounds off their weights)
A good tip is to substract 5-10 % of the claims that is actually being prestented, and you will most likely have the real number.
For example, if someone tells you they lift 400 pounds in bench presses, the real number is probably somewhere between 375-395 pounds depending on what degree of lying/cheating the individual is comfortable with, and at the same time look at themself as "honest people". They would never claim to lift 400 pounds if they only liftet 200 pounds though, because that is going way over the moral compass which is embedded in our own body/system.
So the moral of the story is, dont take ANY claims seriously untill you actually have the facts on the table... We all remember SMM.....
