Kelsey Henson's Height: The 19-Inch Story
This is one of the most-searched questions about Kelsey — and most competitors give only a number.
- Kelsey's height: 5 feet 2 inches (158 cm); her husband Hafþór stands 6 feet 9 inches, making the difference 19 inches.
- Weight: ~52–54 kg
- Body measurements: 34-24-36 inches
Björnsson and Kelsey frequently attend red carpet events together, and the massive 19-inch gap in their heights draws immediate attention. Kelsey has addressed this publicly with humor — leaning into it rather than shying away — which has made her one of the most relatable figures in her niche.
Kelsey Henson and Hafþór Björnsson: Their Love Story
How They Met (September 6, 2017)
Kelsey and Hafþór met on September 6, 2017, when Kelsey was working as a waitress at Earls Kitchen + Bar in Fort McMurray. Hafþór had arrived in the city as a celebrity guest during a strongman competition and visited the bar where she was working.
She recognized him, asked for a photo, and their connection started right there. The couple got married on October 21, 2018.
Family Life
- The couple welcomed their first child, a boy named Stormur Magni Hafþórsson, born at 11:19 AM on September 26, 2020.
- Hafthor and Kelsey lost their daughter Grace Morgan Hafthorsdottir due to stillbirth on November 8, 2023.
- Kelsey is also stepmother to Hafþór's daughter Theresa Líf from a previous relationship.
Their public sharing of this profound loss demonstrates the authenticity that has always characterized Henson's online presence. By sharing their personal story, they hoped to raise awareness about miscarriage, stillbirth, and infant loss — issues that affect countless families worldwide yet remain wrapped in stigma and silence.
Kelsey's second account, @uncensoredmommy, became a dedicated space for that honest conversation around motherhood and grief.

Kelsey Henson's Fitness Philosophy
Kelsey trains at Thor's Power Gym, which she co-owns with Hafþór. Her approach is built around functional strength and consistency — not aesthetics as an end goal.
Key principles she has shared publicly:
- Diet: ~90% clean eating; two cheat meals per month
- Favorite cheat foods: Poutine, cheeseburgers, and pizza
- Workout style: Strength-based; she pulled a 13-ton heavy truck with legs, which made her a sensation on Instagram.
- Brand alignment: Transparent Labs — a supplement company known for clean, evidence-backed formulations
- Content tone: Real workouts, minimal filters, family-integrated storytelling
In August 2019, Hafþór posted a video on his YouTube channel showing Kelsey pulling a Dodge Ram pickup truck on leg day. That clip circulated widely and confirmed her as a serious athlete in her own right — not just a supporting character in her husband's story.

2026 Update: Where Is Kelsey Henson Now?
As of April 2026, Kelsey Henson continues to co-run Thor's Power Gym alongside Hafþór. She remains active on both Instagram accounts, posting fitness content and candid moments from family life.
Her advocacy around pregnancy loss — sparked by sharing Grace Morgan's stillbirth openly in November 2023 — has added a layer of purpose that sets her apart from most fitness influencers. Son Stormur Magni turned five in September 2025. Kelsey continues to hold her NCSO and HSA professional certifications, credentials she earned years before public life found her.
