The Official Gym & Fitness Thread

If I'm reading this right (I'm 5'9")...my max weight would be 180 with my current 10% BF leaving LBM 163. Close enough to my 185 "goal"

 

Just LBM, right? If so, obviously, you're on steroids.

Damn, am I the tallest guy in this thread?!

 

Here's what it said for the chart, btw:

 

At 5'9" , I spent most of the last 10 years hovering between 180-185. Went up to 205 and was strong as hell but everything I enjoyed doing besides lifting took a hit. Slowly been cutting and am currently around the 170 mark (and leaner than I have ever been). The last time I was in the 170s, I was in high school. Honestly I think this is my ideal weight while replacing a few lbs of fat with muscle.

 

I'm 6'1 but way weaker.

I'm 15lbs under the LBM for my height not counting bf. Kinda curious what my bf is now...

 

is the lean body mass 0 % fat then? I'm confused ish....
Because lets say the 6'0 category : thats 184 pounds at say 0 % fat. if i say I'm 20% fat, 184x 1.20 is 220#. Im 235-240..... say @ 20% which would give me 200# of lean body mass and no I'm not on juice either

 

Lean body mass is your total weight, minus your fat (includes muscle, water, organs, bones, etc). No one can be 0% fat.

 

The formula you would want to use is Lean body mass/(1-desired body fat percentage).

So if I am 150.9 lbs of lean mass/ (1-.10) = 167.7 lbs at 10% bf

 

I'm aware of that, i missed the 5-8%. Then with that notion I'm even more over by a long shot.

 

No, technically 150.9 lean mass is quantified as 5-8% body fat i am told

 

so me at 240 @ a number of 20% BF(using a higher bf for argument sake) , if lean body mass is 5-8% then thats is : 240/1.15 to 240/1.12 209-205lbs over their projection of 184. Thats over a 20 pound difference from their number.....

 

Oh okay, I got you. At 235 and 20% bf and 6'0", your LBM is 188. The chart says max is 184, so you're not that far over.

The chart is assuming one has 5-8% bf, but it doesn't matter b/c at that height and weight, muscle mass won't change.

 

Yo math aint right

If the LBM comparison is set at 5-8 % lets just go extreme and say 5%.
If I'm 20% there is a 15% difference between the 2, I .e id have to loose 15% fat.
Thus, @ 5 % id be 204

 

That calculation was for me at 5'9"....you are 6'.

5-8% is not a good for the average male to maintain for extended periods of time.

Regardless, in the grand scheme of things this crap doesnt matter. Use a mirror to judge and everyone has a different definition of "in shape".

 

I was using the LBM calculator at bb.com. I dunno how accurate it is.

 

I wasn't comparing me and you. I was using the Charts data saying LMB is some one at 5-8% BF. I totally agree that 5-8 % is a little to low though but this is just for argument sake of NATTY OR NOT.

 

The chart said (important part in red):

 

yeah i read that after the fact, which made my situation even worse lol

 

I've gone to two other lbm calculators and plugged in your #'s and it gave me 188 each time. So, according to the three LBM calculators and the chart I used, you're 4 lbs over the natural limit, so you're obviously on steroids.

 

I wasnt comparing either....I was simply trying to give you another means of estimating a good goal weight which in my opinion correlates well with the findings that Zach posted.


Body weight - (body weight % body fat percentage)
240-(240*.20)= 192lbs

192 lbs lean body mass / (1 - .10) = 172 lbs at 10% body fat would be a good starting base number.
