The Solidays Challenge 2026 is on the calendar: December 3 through December 17, open exclusively to [solidcore] members. That gives you a few weeks to get ready, and the best time to start training is now.
The strongest finishers don't go from zero to Solidays. They build up: booking consistently, mixing their class formats, and taking recovery seriously. Below are the dates to know and how to set yourself up for your best challenge yet. For how the challenge has grown since 2022, read Shakes of Solidays Past. Stronger for the Solidays starts now.
Mark these now so nothing sneaks up on you.
The December muscle focus calendar is programmed with the challenge in mind, so square away your membership and credits before it drops on November 23.
You don't need to take Signature50 every time to complete Solidays. Mixing in other formats gives your muscles variety and keeps you from pushing to your absolute limit every single day.
Our monthly muscle focus calendar rotates which muscles each class targets, so you build strength evenly and give each group time to recover. December's calendar is programmed with Solidays in mind. When it drops on November 23, use it to plan your weeks: line up the focuses you want, then choose the format that fits how your body feels that day.
Solidays is a marathon, not a sprint. Training smart now means you'll feel strong on day 15, not just day one.
What you do outside the studio matters as much as what you do on the custom-built reformer. Build these habits now so they're automatic by December 3.
