Your upper body looks very good, legs are okayish but considering the issues you have they're actually more than that.
Posing has a lot of room to improve, i know you have never competed yet but I'm telling this because if you look good with that posing if you manage to improve it you gonna look nuts.
I'll keep an eye on your log. Good luck hitting your goals bro.

Those two machines are gimmicks and utterly useless for your purposes. You cannot rely on the body fat percentage that they claim.

He is not close at all. He has a long way to go. The good news is that he is starting at a better place than most of those who will be on stage with him.
To ChemBB, yes, you can get under the weight cap. Get a coach if you need it for nutrition and prep, but absolutely pay for a posing coach.

I think you can make 177, easily. Are dexa scans actually that accurate? Im not trying to be rude but if you are 190, at 9% youre only carrying 17lbs tissue that isn’t considered LBM?

The machines are not all equal. In addition, operators are not all equally skilled. In addition, water, food. In addition, calibration matters and basically dictates the outcome. There is a debate about which calibration is best.
There are disputes over the standard and a lack of information on what to base the standard. It's not like we can butcher ChemBB and heat up the remains to see how much fat we can separate, weigh it, and compare to the measurements to recalibrate. There has been some work with cadavers and animals that were killed afterward, but there has been some disagreement about whether there is enough data to set the machines properly.
There are arguments that Dexa underestimates body fat. So the NHANES calibration addresses that, but here is an argument that the study upon which it was based was flawed and that therefore NHANES overestimates body fat, because it is based upon flawed information in addition to being adjusted to compare to hydrostatic weighing and another method of which I have never heard, both of which, according to this link, are less accurate and therefore are not appropriate standards.

More on Dexa and calibrations.
Note the 2020 return to the classic model over the CDC's NHANES.
Note Figure 3 with Dexa scan printouts like what we saw above in this thread.

"Not All DEXA Scanning Services are equal. Some services use a calibration called ‘NHANES’. The NHANES calculation does a normal DEXA Scan but then will reduce the Lean mass by 5.6% and will add this value to the fat mass."

The below calculator will convert the key results from your NHANES DEXA Scan to the real bodyfat and lean mass figures

As you can see under the graph at the upper right, this is a NHANES result using the subset of white males for data comparison (percentiles)

BUT
The calculator in post # 31 would say ChemBB is only 4.5%, which is way off judging by his photos, so maybe NHANES is the best way to do it, after all.
Sample size of one

Generally speaking, it is the best we have among all the ways to measure body fat.
All of them have limitations, including Dexa.

All the delusional fatties on reddit are arguing for a return to Classic from NHANES because they are getting disappointingly high body fat percentages on their Dexa scans. Obviously, changing the calibration is easier than eating less.
This delusional fatty is using the same conversion calculator that I posted in # 31 (the one that makes ChemBB only 4.5%). Ah, the power of the internet.
All of the below is quoted from Reddit:
DEXA Scan # 1, October 2023:
Total Mass: 153 lbs
Fat Mass: 51.3 lbs
Lean Muscle Mass: 95.9 lbs
This gave me a BF% of 33.6%. Recalibrated calculation: 30.18% BF, 101.58 lbs of lean muscle mass.
DEXA Scan # 1, June 2024, after cleaning up diet and lots of hard work:
Total Mass: 148.8 lbs (my scale at home says 146
)
Fat Mass: 46.1 lbs
Lean Muscle Mass: 96.5 lbs
This gives me a BF% of 30.98%. Recalibrated calculation: 27.35% BF, 102.22 lbs of lean muscle mass. This is closer to what i've seen in other people's estimation of body fat and also what i was getting back from a 4 fold caliper test (I know, i know, these aren't accurate either)....
Hope this clarifies the error rate for some people. Happy lifting!

Um, wow, eight months, and a loss of only 4 pounds, LOL.
Let's use the conversion calculator to make me feel better about my lack of progress! Ironically, this person reduced body fat by only 2.6-2.8% regardless of which method was used. Still fat.

I'll stop now. The bottom line is that the NHANES used in ChemBB's results is probably the most accurate way we have to measure body fat.
At the end of the day, what is really going to matter is how he looks on stage, not what the Dexa says. Are there striations? Is there fat between the muscle and skin? Is that Christmas Tree in the lower back present?
Since he is competing in Classic, striated glutes will not be visible, but it would not hurt to get as lean as possible prior to stepping on stage.
By looking at he photos only, he will make the weight cutoff, but I encourage him to go by photos in all of the poses and his coach's feedback and guidance, not so much by the scale weight and cutoff.

thats very interesting. Of course it isnt a dexa contest, but I find it hard to believe he is going to have to get to a legitimate 3% to make the weight. Most guys in amateur shows can’t really be asked to do that.
In terms of classic— they do have trunks that follow regulations which show glute striation and development if the participant chooses to purchase them, which he would almost certainly have if the dexa is closely accurate.
I would lean more to the potential for the dexa to have been influenced by water, glyocogen and food potentially as I’ve seen these an alter the results. This is another thing fhaf is going to be stripped for the weigh in, so when OP is dry especially, i bet he can make the weight and probably get well under the cap In 24 weeks. That timeline looks really good to lose the amount of weight necessary so hopefully it goes smoothly

Thanks man, means a ton coming from you!
I feel like I look about 11-12%. I ordered skinfat calipers, will be curious what they say as well.
Also, "lean" mass includes water + glycogen, which can easily be +30lbs
bro if I'm not mistaken, I read that you had a heart attack at 30, and are you now preparing for a race??
