What muscles do squats work?
How often should I do squats?
How many reps of squats should I do?

My waist is 26 inches, which makes me feel bad because I am only 84 pounds, so I think my waist should be smaller than that, especially since I see celebrities with waists of 24 inches, despite weighing at least 40 pounds more than me. My waist-height ratio indicates I'm "slim" but it doesn't take my weight into account.

Insert your height and weight. It'll predict the rest of your body measurements. How do they compare to your actual measurements?
I'm curious because, for someone who's 5'0 and 84 pounds, I'm slightly fatter than it predicts for me to be. It predicts that I have a 28 inch chest, 22 inch waist, and 32 inch hips. I have a 30 inch chest, 26 inch waist (sigh), and 33 inch hips. See prediction on left side & reality on right side:

I'm mostly concerned about the waist. Is it normal to have a waist that is 4 inches larger than predicted? Especially for someone who's underweight. My "waist-height ratio" says that my waist is "slender and healthy", but that doesn't take into account that I'm underweight, so I should have a smaller waist.

So how about you? How do your waist measurements compare to what's predicted when you insert your height and weight into that calculator?

Thick legs/thighs doesn't mean she's fat🤔😏

Bruh I just found a lump in between my butt cheeks
I’m not sure which kind of lump, though
I also found some hair there, too

I'm 83 pounds at 5'0, which is a BMI of 16.2, which is on the verge of the "starvation" category according to the World Health Organization.
But as per my calculations, my waist-hip ratio (WHR) is.83. Apparently that's the average WHR for a woman, but apparently that's classified as "overweight" or even "obese".

The average woman is overweight so that makes sense for the average woman, but literally nobody can tell me that 83 pounds is overweight & that I need to lose weight to be healthy.
But apparently a large part of the connection between WHR & poor health is due to heart disease. Heart disease runs in my family VERY, VERY badly. Could that be the reason my WHR is relatively high? But I'm also sedentary, so maybe that's a factor?
If you're not fairly certain that you know the answer, please choose the first option. I want input mainly from people who know what they're talking about.

Im 5ft1
And Im currently 160 pounds

Which range should be ideal for me?

I've heard people say that vomiting feels good because it relieves the nausea. Personally I think it feels awful regardless, and I would prefer nausea to just go away without needing to vomit in order for it to do so. How about you?

it may sound like an excuse, but because of school. I gained weight because of stress and ton of poor quality food. I do not understand how it could happen, I used to have 130 lbs, now 190. how to drop as quickly as possible, I have the last year of study and it would be the hardest part of my life :(
