Solidays is coming back very soon. First, a visit from the shakes of Solidays past.

Every December, right when calendars fill up, tens of thousands of us sign up for the Solidays Challenge. And we do mean us. We opt in right alongside you, and we have to hit our 6 or 10 classes to earn the prize just like you do. And together our legs shake halfway through class and we all book the next one anyway. 

Before this year's Solidays Challenge kicks off…we wanted to look back at how the challenge started, how many of us have taken it on, and what we've earned along the way.

‍

What Is the [solidcore] Solidays Challenge?

The Solidays Challenge is [solidcore]'s annual holiday challenge. We've run it every December since 2022. Everyone sets a class goal, takes class for about two weeks during the busiest month of the year, and earns a prize by hitting that goal. In 2023, 2024, and 2025, the Solidays Challenge goals were 6 or 10 classes across 15 days. 

Each year has its own theme, its own prizes, and its own set of stories. Here's the full history, and if you're looking for this year's dates and prizes be sure to follow us on Instagram for the full announcement. 

New to [solidcore]? It's slow, controlled, full-body strength training on our custom-built reformers. Our new client guide covers what to expect.

Why Is the [solidcore] Solidays Challenge in December?

We hold it in December on purpose. It's the hardest month of the year to find 50 minutes for yourself. Your calendar fills up, and your own goals are the first thing to come off it. 

So in the season of giving, give something to yourself. 50 minutes of not answering emails. 50 minutes of not thinking about the list. 50 minutes that are yours and yours alone. The strength you build under the blue lights doesn’t stay there. That’s why we do this at the height of the holiday season, whenever everything else is asking for your time.  

Solidays isn't a competition. You set the goal, and you're the only one keeping it. The prize isn't the point. What you earn is the proof: you went when it was inconvenient, when you didn’t think you had the time for yourself, when it was cold, when you already had somewhere to be. Strength is a habit. This is two weeks of practicing it for you. 

Come January, you're not starting. You're continuing.

Solidays Prizes, Year by Year

Everyone who hits their goal earns an exclusive prize. You can't buy it, only earn it. 

Solidays 2023. The challenge was part of our joy in the work holiday campaign. Six classes earned a limited-edition [ ] beanie, and 10 classes earned a limited-edition [ ] crewneck. Everyone who finished also got a Solidays badge in the app.

Solidays 2024. The theme was 50 minutes for yourself at the busiest time of year. We partnered with Tower 28 on the prizes. Six classes earned a Tower 28 x [solidcore] recovery kit with the SOS spray and a co-branded towel. Ten classes earned the kit plus a limited-edition [solidcore] hoodie. The hoodie wasn't for sale anywhere, so the only way to get one was to earn it, and TikTok started calling it the "Birkin hoodie."

The Solidays 2024 prizes: the Tower 28 x [solidcore] SOS spray and co-branded towel for 6 classes, plus the black [solidcore] hoodie for 10. It was never sold.

‍

Solidays 2025. The theme was 15 Days of Strength,and it was the first year the challenge was for members only. Six classes earned a Salt & Stone Bergamot & Hinoki deodorant and mini body mist duo. Ten classes earned the duo plus a Solidays-exclusive [solidcore] mockneck sweatshirt. By the last few days, people were filming themselves checking off the final box on the studio tracker, and it turned into a trend. Our coaches were posting their own Solidays updates right alongside yours.

The Solidays 2025 prizes: the Salt & Stone Bergamot & Hinoki deodorant and mini body mist for 6 classes, plus the heather gray mockneck with an embossed [solidcore] logo for 10. You could only earn it.
