Uee shares a Hyrox training update
Uee, the After School member turned actress, has given fans a detailed look at her preparation for a Hyrox competition. In a social media post on 3 November, she said she had not realised how intense the training would be, and shared body composition records showing how her measurements had changed over several months. Koreaboo reported the update.
The post matters beyond the numbers. Hyrox is a fitness racing format that asks competitors to combine running with functional workout stations, so the training block has to build endurance and strength at the same time. For a performer whose public image has long been tied to dance and stage work, the update is a rare window into a different kind of physical challenge. It also frames the effort as a work in progress rather than a finished transformation.
The figures Uee posted
According to the records Uee shared, her skeletal muscle mass stood at 23.9 kg on 3 November, with body fat at 19.0% and body fat mass at 10.3 kg. The trend across the preceding months is the more revealing part. Her skeletal muscle mass was 22.5 kg on 9 July, dipped to 21.8 kg on 10 August, then rose to 23.9 kg by 3 November, a gain of 1.4 kg over roughly four months.
Her body fat percentage moved in the opposite direction after an August peak. It was 25.2% on 10 August, 23.0% on 24 August, 20.2% on 1 October and 19.0% on 3 November, a fall of 6.2 percentage points in about three months. Body fat mass dropped from 13.6 kg to 10.3 kg over the same period, a reduction of 3.3 kg.
These are the readings Uee chose to share, not independent clinical measurements, and they should be read as her personal tracking rather than a medical assessment.
Why Hyrox preparation is different
Hyrox events combine repeated running with stations that test strength and power, which is why preparation can look different from a standard gym programme. Competitors need a base of aerobic fitness for the running segments and enough resistance training to handle the station work without fading. That mix helps explain why Uee's post focuses on both muscle gain and body fat reduction rather than weight alone.
The post did not say which Hyrox event she is targeting or when it takes place. What it does show is that the training has been demanding enough to prompt a public note about its intensity. For readers who follow fitness content, the useful detail is the length of the block: the records span from July to November, suggesting a sustained build rather than a short crash programme.
For a celebrity with a dance background, the running volume and station work can be a fresh test. Dance training builds stamina and coordination, but Hyrox adds paced running and loaded movements that require a different kind of conditioning. That may be why the preparation has felt so intense, though the post does not go into the details of her weekly schedule.
Her earlier exercise routine
Uee has discussed her exercise habits before. On a YouTube channel, she said she had bought a machine known as the 'Stairway to Heaven' and used it for 4,000 repetitions a day for more than a year. She also stressed the importance of hydration and a healthy diet, presenting consistency as the key to her routine.
Her past comments about body image add context. On KBS2's Problem Child in House in 2023, she said she debuted with 'honey thighs' but was not satisfied with her body after extreme dieting. She later described how consistent exercise helped her regain confidence. That history makes the Hyrox update more than a set of figures: it is part of a longer conversation she has had about training, self-image and the pressure to look a certain way.
What the numbers can and cannot tell us
Body composition readings can be useful for spotting trends, but they are not a complete picture of fitness. Hydration, the timing of a measurement and the device used can all affect the numbers, which is why a single reading rarely tells the whole story. Uee's post works best as a progress log from one person during one training block.
The emphasis on gaining skeletal muscle while body fat fell is also notable. It is a different framing from a simple weight-loss story, and it shifts attention towards strength and performance. That does not make the figures a standard for anyone else. Readers can take interest in the trend without treating Uee's numbers as a target, and without assuming that the same approach would suit a different body or a different goal.
The numbers also come with a timeline, which is more useful than a single before-and-after comparison. The muscle gain did not follow a straight line: it fell in August before climbing through the autumn. That kind of fluctuation is common in training blocks and is one reason trends matter more than individual readings.
The public side of a private challenge
Celebrity fitness posts sit at an awkward intersection of personal challenge and public expectation. Sharing detailed data can invite scrutiny, especially when the person posting has spoken before about body image. Uee's earlier comments about extreme dieting make the context important: a post about getting stronger can be read differently from a post about getting smaller.
The source does not set out her reasons for posting the records beyond the Hyrox context, and the post itself does not present them as advice. That distinction matters. The update is a snapshot of her own preparation, not a template for fans. The interesting question is how much detail public figures choose to share when a fitness goal becomes part of their public story.
Takeaway
Uee's Hyrox update is, at its core, a training milestone. By the records she shared, she gained 1.4 kg of skeletal muscle and reduced body fat by 6.2 percentage points over the months leading to 3 November. The post also adds to a longer record of her talking about exercise and body image, from the 'Stairway to Heaven' routine to her comments about extreme dieting.
The takeaway is not that her figures should be copied. It is that the post documents a specific challenge and a sustained routine, with the demands of Hyrox as the backdrop. Fans can follow the journey for what it says about preparation and consistency, while keeping the numbers in perspective.
