Jrod - looks very good. I have never seen a competitor overcome weak calves, only example was Aaron Baker and that was due to implants, check out pics of him with WBF to when he came back to IFBB, went from 14" to 20" nice.
I think Jrod is more like 5'8" so it is possible he is clean and with small joints to cause illusion. Here is great article on contest weights of naturals compiled by Leangains.com author. It is pretty accurate.
"Martin Berkhan of Leangains.com has a somewhat simpler model than Casey’s, also based on his observation of top level natural bodybuilding competitors who are contest lean (e.g. 4-5% body fat).
His equation is:
Height in centimeters - 100 = upper limit of weight in kilograms in contest shape.
So take your height in inches and multiply by 2.54, that’s your height in centimeters. Subtract 100 and that’s your predicted maximum weight in contest shape (which is 5% body fat or less for males) in kilograms. Multiply that value by 2.2 to get pounds. So let’s look at body weight at 10% body fat using the same heights I used for Casey’s calculator. I’ve also calculated out lean body mass at 10% body fat.
Height Weight at 5% Body Fat Weight at 10% Body Fat Lean Body Mass
5′8″ 160 lbs. 170 lbs. 153 lbs.
5′10″ 171 lbs. 180 lbs. 162 lbs.
6′ 182 lbs. 192 lbs. 173 lbs.
While not identical, these values are certainly right in line with Casey’s calculator. I would note that contest lean bodybuilders are often highly dehydrated and may be glycogen depleted and this will tend to lower the measurement of lean body mass. We might realistically add 5-10 pounds of lean body mass to the above values to account for dehydration/etc. With that adjustment, they are more or less identical to Casey’s values "
