How accurate are the max charts??

[D_Master]

I was wondering how accurate he max charts are, or the max calculators on the internet for determining my max on the bench. I have gone to several different places on the internet and looked at the chart they have hanging in the gym and they differ by as much as 10 lbs what i should be able to lift. Just the other day i lifted 190 x 9, which on the chart says I should be able to max 250. Not bad for a guy weighing in at 170, but a couple weeks ago I maxed and barely was able to hit 240. I can't imagine that I could go up 10 lbs in 2 weeks, so i just wondered how accurate these charts and max calculators were?

Also when I lift weights in the range of 185-205, i can rep that weight, but the 1st several lifts it doesn't feel like i will be able to get up to the 8 reps. Then when i maxI'm below what it says I should be able to lift for the amount of reps i get at certain weights. I was wondering if anyone had any insight on why that might be? Doesn't seem like the 3rd-6th rep should be as easy or easier then the first few.

Umm, charts are just a rough estimate?

You're thinking too much. Stop looking at charts.

lifting isnt complicated; you dont need to overthink it

I always looked at the Max Chart as a plus as it will save you time in trying to figure your max rep weight without actually doing it which in my opinion will curtail injuries as without it you'd pick a weight that just might be way to heavy and throw your back out especally if your going to Clean and Press, Deadlift and Squat like I have been doing and puts you in a good frame when lifting.

Just my opinion when getting back into training after a long layoff it saves the body from finding that max and your'll have a target weight to aim for even if the Max Chart isn't 100% correct but is close enough and is good for beginners starting out.
