Strictly Come Dancing’s Rachel Riley: I’m losing my boobs
Rachel Riley once surprised fans with an unusually honest confession about her time competing on Strictly Come Dancing — revealing that the intense training schedule didn’t just improve her fitness… it completely changed her body shape, including something she hadn’t expected at all. 💃✨
The popular TV mathematician admitted that weeks of rehearsals had caused noticeable weight loss — so much so that her bras no longer fit properly, prompting her to joke that she was “losing her boobs” during the competition.
But behind the light-hearted comment was a real glimpse into how physically demanding Strictly actually is.
A transformation she didn’t expect when joining Strictly
When Rachel first stepped onto the ballroom floor, she already had a reputation as one of Britain’s most recognisable brainy TV personalities thanks to her role on
Countdown.
Fans knew her as sharp, calm, and quietly confident.
What many didn’t realise was how dramatically Strictly would reshape her daily routine — and her body.
Speaking during her time on the show, Rachel explained that constant rehearsals meant she was living almost entirely in training clothes, rarely even thinking about regular outfits while adjusting to the competition’s demanding schedule.
And then came the unexpected change.
“My bra is definitely looser”
Rachel openly admitted that the physical intensity of dance rehearsals had altered her proportions.
She explained:
- her costumes needed adjusting
- her weight had shifted
- and her usual measurements no longer applied
“I don’t know what size I am because I live in training gear,” she said at the time.
It wasn’t a complaint — more an observation about how quickly the transformation happened once rehearsals began.
Professional-level dance training can burn thousands of calories per week, especially during long rehearsal days leading up to live performances.
Strictly training is tougher than viewers realise
From the outside, Strictly Come Dancing looks glamorous.
Sequins.
Spotlights.
Smiles.
But contestants regularly describe the experience as one of the most physically exhausting challenges they’ve ever attempted.
Rachel confirmed she was using muscles she’d never used before, something nearly every celebrity participant eventually says during the competition.
Daily rehearsal schedules often include:
- multiple choreography sessions
- strength and posture training
- costume fittings
- camera blocking
- and live-show preparation
It’s closer to athlete-level conditioning than casual dance practice.
Learning to feel confident on the ballroom floor
Rachel also admitted she’d previously felt self-conscious about certain aspects of her appearance — particularly her figure.
But the show changed that mindset.
She explained that once choreography required her to perform confidently in front of millions of viewers, worrying about body image simply stopped being useful.
“If I have to shake my butt,” she joked, “there’s no point being shy.”
That shift in confidence is something many Strictly contestants describe after completing the competition.
Ballroom performance demands presence — and presence often replaces insecurity.
The unexpected effect on her home life
It wasn’t just her wardrobe that changed.
Rachel also revealed that the intense physical strain from rehearsals made everyday things surprisingly difficult — even hugging her husband at the time, Jamie Gilbert.
After long training days, she joked that she was often too sore for normal affection.
“He’ll say, ‘Where can I hug?’” she said.
“And I’ll say, ‘My head’s fine!’”
It was a humorous moment — but also a reminder of how demanding the competition really is behind the scenes.
Why Strictly transforms contestants so quickly
Each year, viewers notice dramatic physical changes in participants.
Weight loss.
Improved posture.
Stronger core muscles.
Greater flexibility.
Rachel’s experience wasn’t unusual — it was simply more openly discussed than most.
Unlike gym workouts, ballroom dancing combines:
- cardio
- strength training
- coordination
- endurance
- performance stamina
All at once.
That combination explains why contestants often describe the show as life-changing physically as well as mentally.
Fans loved her honesty about body changes
Rachel’s comments stood out because they felt refreshingly real.
Rather than presenting the transformation as glamorous, she described it exactly as it was:
unexpected
fast
and slightly confusing at times
Viewers appreciated that honesty.
In a television environment often focused on appearance, her relaxed attitude helped normalise the idea that body changes during intense training are completely natural.
From mathematician to ballroom competitor
Before joining Strictly, Rachel was already widely known for bringing numbers to life on British television.
Her role on Countdown made her a household name, admired for both intelligence and approachability.
Competing on Strictly introduced a completely different side of her personality:
playful
determined
and surprisingly fearless on the dance floor
For many viewers, it was the first time they saw her outside a studio puzzle format.
A reminder that dancing is serious athletic work
Rachel’s story highlights something longtime Strictly fans already know well:
ballroom dancing isn’t easy.
Even contestants with strong fitness backgrounds often struggle during the first weeks of rehearsal.
Learning choreography under time pressure while performing live each weekend requires both physical stamina and mental focus.
Rachel’s experience losing weight — and even needing costume alterations mid-series — shows just how intense that process can be.
Why viewers still remember her Strictly journey
Years later, Rachel Riley’s comments about “losing her boobs” during rehearsals are still quoted whenever people talk about how demanding the show really is.
Not because the remark was dramatic.
But because it was honest.
It captured something viewers rarely see behind the glittering ballroom lights:
the effort
the soreness
and the surprising physical transformation that comes with stepping onto the Strictly dance floor.
And for fans watching from home, it made one thing very clear:
those routines might look effortless on Saturday night…
but they’re anything but easy in real life. 💃✨

Strictly Come Dancing star Rachel Riley says dancing hard has made her lose her boobs. The mathematician genius has lost so much weight that her bras no longer fit.
‘I don’t know what size I am because I live in training gear,’ Riley said. ‘A lot of my Strictly outfits are being altered and my bra is definitely looser. My body feels completely different. I’m using muscles I’ve never used before. I’ve always been self-conscious about my big bottom, but if I have to shake my butt, there’s no point being shy.’
The dancing has also taken a toll on her love life as the 27-year-old says she can’t even hug her hubby because she’s so sore.

Riley said: ‘Jamie will say to me “Where can I hug?” And I say “My head’s fine!”’
