- Hilary Duff has been named the face of Ladder's new "Hilary Duff Trains on Ladder" campaign, the Austin-based app's first-ever celebrity partnership.
- The campaign taps into a measurable cultural shift: the share of female Ladder members defining fitness success as gaining strength has quadrupled since joining the app, jumping from 9.7% to 41.5%.
- Duff says strength training transformed how she performs on stage and carries her four kids, making the deal a naturally authentic fit with her public persona heading into her world tour.
- Ladder now counts 400,000 members worldwide, with women making up roughly 80–90% of the base, and recently secured $105M in combined investment funding.
Hilary Duff, the actress and singer has been named the face of Ladder’s brand new “Hilary Duff Trains on Ladder” campaign, marking the iOS strength training app’s first celebrity partnership since launching in 2020.
Duff, who once favored cardio over weights, credits the switch to strength training for changing how she feels, moves, sleeps, and performs.
With her debut on Atlantic Records album luck… or something debuting at #3 on the Billboard 200 in February 2026 and a sold-out “The Lucky Me World Tour” kicking off June 22, including stops at Madison Square Garden and the Kia Forum, the timing couldn’t be sharper.
Beyond music, Duff also serves as Chief Brand Director for home fragrance line Below 60° and holds investment stakes in makeup brand Nudestix and children’s label Happy Little Camper.
This move reflects a wider 2026 trend of targeted brand partnerships, seen in campaigns like Demi Lovato teaming with TheraBreath on its “Get Ready. Fresh. Go.” push and Duncan James linking with Coors for the “Cold Coorus” activation.
For Ladder, which previously partnered with Diplo’s Run Club for a nationwide strength training tour, this is a major escalation. The app holds a 4.95 App Store rating across 150,000+ reviews, was Apple’s 2025 Editors’ Choice, and is backed by $15M in Series B funding plus a $90M growth investment from General Catalyst.
Takeaways
This deal is smart on every level. Duff isn’t just a recognizable face, she’s a mom of four preparing for a global tour, the exact profile of a Ladder user. Authenticity is the currency of modern brand deals, and this one has it in full.
Ladder isn’t spending its $90M war chest on a random celebrity endorsement; it’s making a precise cultural statement that women’s fitness is moving from the treadmill to the weight rack.
And with luck… or something already topping charts in six countries, Duff is riding one of the biggest cultural re-emergence moments of 2026. That visibility gives Ladder massive reach into a demographic (millennial women) who are already the core of its membership.
Does Duff’s authentic “mom on the go” narrative make her more or less effective than a traditional athlete spokesperson for a fitness app? With 80–90% of Ladder’s members being women, does leaning entirely into a female-first brand story limit Ladder’s growth ceiling, or is it exactly the right niche play?
