In terms of height, muscle density, or weight?
In the Midwest you will find foids with an extreme of all three. I walk by the fattest fucking foids on the planet every day. Even when I used to go near the border of Texas (where it's all comically overweight Latinxes, especially the closer you get to McAllen/Brownsville/Laredo) the density of overweight/obese women seems much higher up here than it was there.
If I'm out for long enough I'll see a foid who is 6'3" or 6'4", but most of them are fairly skinny. I've seen some 6'0"-6'1" foidchonkers out here who also just so happened to be extremely obese. Like those specific foids must have weighed 400+ lbs minimum. Those were probably the biggest I've seen counting height and weight.
Though when I also lived in Texas it wasn't uncommon to see 4'10" Latinxfoids who were shaped like a yoga ball.
The tallest gymfoids I've seen with good frames were probably like 5'10"-5'11" so I haven't seen anything like what you're describing.
