Winter Arc 2026: one mountain, until December 31

The Winter Arc is the last three months of the year spent locked in: training, eating and sleeping on purpose while everyone else waits for January. Here is how to run it, a 13-week gym plan to follow, and how to keep score one week at a time.

What is the Winter Arc?

The Winter Arc rules that actually work

  1. Judge the week, not the day

    Pick a weekly target you can keep — three training days is a solid default — and count the weeks you hold. A rest day is part of the plan, not a failure.

  2. Train with progressive overload

    Add a rep, a set or a small amount of weight when you hit the top of your rep range. Three months of small increases is where the visible change comes from.

  3. Eat enough protein

    Around 1.6 g of protein per kg of bodyweight per day is a common evidence-based target for building muscle. Hit it on training and rest days alike.

  4. Protect your sleep

    Seven to nine hours. A short night is a reason to train a little lighter, not to skip — and not a reason to abandon the arc.

  5. Make it visible

    Track every session and every week held. Seeing the climb is what keeps you going in week 7, when the novelty has worn off.

Run your Winter Arc in Stance

Stance has a Winter Arc built in. Pick your day 1, and your season is drawn as a mountain: one point per day, one milestone per week, the summit on December 31.

Every session you log moves you up the climb. A week is held when you reach your own weekly target, and the number that measures your arc is the count of weeks held.

Winter Arc FAQ

When does the Winter Arc start and end?

The Winter Arc traditionally runs from October 1 to December 31 — 92 days, or about 13 weeks. In Stance you can pick your own day 1, and the summit is always December 31.

Is the Winter Arc 90 days?

Close: October 1 to December 31 is 92 days. People often call it a 90-day challenge because it is roughly three months.

Can I start the Winter Arc late?

Yes. Starting late is better than waiting for January. In Stance you choose your day 1 and the arc runs to December 31, with at least four weeks to climb.

How many times a week should I train during the Winter Arc?

Three to four sessions a week is enough for most people to make visible progress. Consistency across 13 weeks matters more than any single week.

What if I miss a week?

Keep climbing. The arc is measured in weeks held, so one short week does not erase the others — the next week is a new milestone.

Is the Stance Winter Arc free?

Stance is free to download on the App Store and the Winter Arc is part of the app. The Active and Elite subscriptions unlock the full AI coach.
