What would be a good weight for a 5'8" 18F

Mimi2003_

My starting weight is 126, and I am wondering what would be a good stopping point.

126 is a perfectly healthy weight for a person your height and age. Which direction were you planning to go?

edit: a word

Well I wanted to get down to 115 so my running times would be faster. Just generally I feel fat, and prefer the skinny look. At 126lbs I look sort of chubby.

The medical chart said a normal range for your height is 125 lbs to 158lbs so it depends where you feel the most comfortable more or less pounds.

I mean, I guess you are technically an adult, but I don't think you need to aim quite so low. 115lbs on someone as tall as you are is flirting with skeletal. Have you considered body recomposition instead, where your weight stays the same but you reduce bodyfat and increase muscle mass?

Slightly shorter than you, and the lightest I was as an adult was 124, and I was plenty thin, but strong. At 115 I would start to wonder if your body would be strong enough and have the reserves to complete your runs or if you'd actually harm your runs even more. I might have carried more muscle than you are at that time, but I doubt that even as an extremely fit athlete/runner you would be below 120 at your height, and that would have NO reserves and will mess with other things (such as your monthly cycles).

Honestly I'd suggest reaching out to a sports doctor to discuss what might be safe and effective.

Yup, if you have a running coach at school, they'll give you training and nutrition tips to lean out for whatever track and field specialty you're working on.

Leaning out and getting light is one thing, reducing the probability of injury is another. If you watched the Olympics this year, exactly NONE of those women are simply "small"

🗣️ They're jacked and stacked!

Especially lower body 😍

Try recomp as mentioned above...and patience.

It doesn't sound as if reducing your weight would be a "good" fit from the perspective of health. Health being a somewhat important "thing" for most people Injury management and optimal training if nothing else both depend on receiving adequate calories. At a BMI of 19 your self description of "feeling fat and chubby" as opposed to fit and normal weight would raise concerns not for your weight... but about your perception of it!

At 18 your body is still in the process of changing because of puberty (It can continue to around the age of 21). That consistent body shape that you had when you were a younger teen may simply no longer be achievable without putting your health at risk. This is partially because of this wonderful thing that female-born humans have called a uterus. This annoying little bench swells and bloats and generally makes a nuisance of one's self. It generally is the reason that people who are slim seem to think that they are chubby. And I hate to break it to you, no matter how much you lose, it will still be there and it will still stick out a little bit because that is what it, as an organ is supposed to do. Whenever someone who is slim who things that they are a bit chubby, I always feel the need to post a link to this amazing thread:

Seriously, if you're an athlete you really don't want to go slimmer, it's unlikely to improve your times and in actuality it could very well make your times worse. I'm not sure what distance you run, but I suggest looking at elite athletes in that discipline and then look at their bodies. Elite athletes are not slim. They are ripped. They may not weigh a lot but the have the best trainers and nutritionists in the world and they are very well calibrated machines. Their weight control is very carefully monitored.

For reference:
Elaine Thompson-Herah is 2 inches shorter than you and weighs approx 123lbs


Oh an in answer to your question from the title: 125 lbs to 158lbs.

Here she is winning the 100m women’s race:

If your goal is to run faster --- I would not focus on your weight at all.

Increasing base mileage per week (even at a slower pace), adding interval sprints on short runs for speedwork, and adding hills or doing speedwork on hills will all help increase your overall pace.

And strengthening exercises as well to build a bit of muscle.

As far as you 'feeling' chubby at 126 at your height....my initial reaction would be that that has to be simply in your head. I am ~5inch shorter than you and have weighed ~114/115 before and was definitely 'skinny' and some people even asked me if I was sick....so what other people see and what you see can easily be very far off from one another.

I know that different weights simply look different on different people but it's extremely hard for me to imagine anything other than a definitely skinny person when you put your weight and height together.

Focus on the above if you really want to increase your running pace...but you also have to be fueling yourself properly....I always take a gel with me when I'm running because my run takes me ~1hr...so I eat it at around 30-45 minutes. Otherwise, I just can't get more mileage in.

I've been 5'8" since I was 13 and I was 135 lbs at that age....skin and bones. As an adult, around 155 lbs works well for me, though my goal is around 145. If I was you, I would start thinking about weight training to complement your running. Losing weight at this point might not assist you in your goals.

I was 5’8”and 125 when I was 18.
In part because I didn’t always have much to eat. But also because I was riding my unicycle or bike everywhere, if I wasn’t walking. And I did a lot of walking.

I was very thin. Very. Thin. (this is how I know me at 275 wasn’t from “big bones”)

You’re already at a very low-normal BMI.
Take the advice given. Work your muscles. Get better at running.
Don’t focus on getting skinnier.
