Winter Arc 2026: My Rules, Dates and Free Workout Plan

By: Lindsey Bomgren, CPT | September 23, 2026

It’s officially time to start your winter arc, and these are the exact rules I’m following to feel my best by the end of the year.

The winter arc, commonly referred to on social media as the lock in challenge, is a period of self-improvement that includes physical, mental and spiritual goals and habits. Most people follow it for about 12 weeks from October 1st to December 31st, but you can start at any time. 

In this post, I’ve outlined my personal winter arc rules along with a 12-week Winter Arc Workout Challenge with daily guided workout videos to help you achieve your goals.

Don’t wait for January 1st! If you start your winter arc now, you’ll go into the New Year already feeling like the leveled-up version of yourself.

What Is the Winter Arc?

The winter arc is a season of focused, personal growth where you set intentional goals and build consistent habits around fitness, mental health, mindfulness and lifestyle. It typically takes place during the winter months, giving you a defined stretch of time to focus on yourself before New Year’s Day.

The term winter arc comes from Gen Z slang on TikTok and plays off the idea of a “character arc,” or the growth or transformation a character experiences in a story. The trend has since evolved into what is also called the “great lock in,” or “winter lock in,” a self-improvement challenge where you focus on becoming the version of yourself you want to be.

I see the winter arc as an opportunity to reset and realign my daily actions with my values and goals. Rather than waiting for New Year’s resolutions to make a change, it gives me a defined season to focus on the habits that help me feel my best.

There are no universal rules for a winter arc. It’s customizable to your personal goals and needs, whether that means prioritizing workouts, nutrition, sleep, mindset, faith, reading or other lifestyle habits. I created my own winter arc rules based on how I wanted to feel by the end of the year and the tangible steps I could take to get there.

When Does the Winter Arc Start and End in 2026?

The 2026 winter arc generally runs from October 1 through December 31. While the trend is often described as a 90-day challenge, there’s no official winter arc start date or required length. Starting earlier or later is completely fine.

For some, a winter arc can be a way to be more intentional during the winter months, when shorter days, colder weather and less time outdoors can contribute to the winter blues. Start when you’re ready!

Who This Winter Arc Plan Is Ideal For

Anyone can participate in the winter arc challenge by adapting it to their personal goals and needs. This 2026 winter arc challenge is ideal for anyone looking to:

  • Prioritize consistency during the 12-week winter arc
  • Fuel their body with nutritious meals
  • Improve sleep quality and quantity
  • Spend daily time in their faith

My Winter Arc Rules

These are the exact winter arc rules I’m following for my 2026 winter arc. The goal of committing to these rules now is to start the New Year feeling like the upgraded version of myself, with consistent, healthy habits already in place.

I recommend using the sample rules below as a guideline to develop your own personal winter arc plan.

Winter Arc Rules (Template):

  1. Choose your dates. For 2026, the general winter arc window is October 1st-December 31st, although you can choose an earlier or later start date and make the challenge shorter or longer.
  2. Pick 3-5 habits to focus on.
  3. For each habit, set a measurable goal.
  4. Track daily and review weekly. (Download my free habit tracker PDF to track your progress.)
  5. Don’t “start over” for a missed day. Just resume the next day. Consistency is more important than perfection!

My top tip to be successful in the winter arc challenge is to start small and focus on habits you know you can stick with. Think of them as quick wins that help you build momentum.

1. Consistent Fitness Routine

2. Healthy Eating

Proper nutrition provides the fuel your body needs for performance and recovery, while also helping you build muscle, lose fat and boost your energy. I feel best when I prioritize high-protein snacks and meals, as well as fresh produce, in my diet. Exercise is the stimulus, but nutrition is what determines how effectively your body adapts and progresses.

3. Prioritizing Sleep

  • 7-8 hours of sleep
  • No working or screen time 1 hour before bed
  • Phone on “Do Not Disturb” from 9PM – 7AM

4. Daily Reading

  • Morning routine: 5:30AM alarm during the week to read from 5:30-6AM
  • Start every day reading my Bible for a minimum of 15 minutes
  • Journal prayers/devotionals and gratitude/meditation daily

5. Cold-Weather Resilience

  • Daily walks in cold weather to get outside and contribute to 10K steps a day. 
  • Cold plunge 4 times a week to build resilience and boost energy. Practice breathwork during cold plunge to regulate the nervous system. 

6. Sabbath Rest Every Weekend

  • Choose 1 day per weekend to sabbath/rest from work and chores (as much as possible)

7. Intentional Planning and Organization

  • Weekly planning meeting with my husband once a week 
  • Declutter or organize one area of my home each week

Workout Plan PDF Details

1. Gym Equipment Needed:

A Set of Dumbbells (Discount Code: NML5). Most of the daily workouts require a set of free weights. Each weight training workout will have a recommended dumbbell weight, usually between 15-30 pounds. You want a weight heavy enough that your last few reps are a struggle, but you are still able to complete the workout with good form.

Optional Exercise Equipment: Mini Loop and Long Loop Resistance Bands (Discount Code: NML), Pull Up Bar and Bench/Box/Chair.

2. Time Requirement: 

Workouts are 20-30 minutes per day, 5 days per week.

This plan includes 2 rest days per week. You get to choose which days are your rest days. I suggest resting after day two or three (Wednesday or Thursday) and then again after day five (Sunday). OR completing days 1-5 and then resting on days 6-7 over the weekend. The goal is to make this plan work for YOU!

3. Fitness Level:

Intermediate to advanced, with modifications offered for all fitness levels in the daily workout videos.

4. Cost:

FREE! No sign up needed.

FAQs

What is the winter arc?

The winter arc is a personal self-improvement challenge focused on building consistent habits during the winter months. There are no universal rules, so you can tailor your winter arc to goals like fitness, nutrition, sleep, reading, mindfulness or other areas of personal growth.

How long should a winter arc last?

There is no set list of rules about how long a winter arc should last, but most people keep it around 12 weeks. This is long enough to build sustainable habits and see progress, but short enough to feel manageable and keep your motivation high. The most common time to start your winter arc is October 1st, so you complete the challenge before January 1st.

Is the winter arc for bulking or cutting?

The winter arc can be used for either, but it doesn’t have to be focused on changing body composition at all. Your goals might include building strength, improving fitness, eating more intentionally, getting better sleep or layering healthy routines. Choose goals based on what you want to prioritize during your winter arc.

Why is the winter arc popular on social media?

The winter arc is popular on social media because it reframes the time of year that’s often associated with burnout, low energy and the “winter blues” into a time for growth and self-care. As a personal trainer, I prefer this over other workout challenges because it combines intentional structure with flexibility and adaptability.

Can I customize the winter arc to my own goals?

Yes, the winter arc is completely customizable to your personal goals. It’s meant to be a seasonal reset that you shape around what matters most to you and your well-being. Some people focus their winter arc goals on fitness goals or health habits; others use it for creativity, mental health, reading, career growth or even rest and slowing down. It all depends on your personal goals!

If your focus is fitness, you don’t need to go to the gym five times a week to participate in a winter arc. You can choose at-home workouts, walking, stretching or any other activities that fit your goals and lifestyle. To track your progress, use a habit tracker, calendar, journal or notes app to record your habits and check in on your progress each week.

8 weeks got me moving again postpartum!

January 14, 2026

I started this winter arc program the last 2 months of the year and it was perfect to keep me on track through the holidays and set me up for the new NML program drop in January! It was awesome to commit to 2 weeks at a time x4, at 4 months postpartum, and actually complete it! I lived that it was all programs that I’ve done before so it was familiar but still challenging.
