Join the Great Lock In: A Global Movement for Self-Improvement

An emerging trend known as the Great Lock In is gaining traction across social media platforms, encouraging individuals to commit to a structured self-improvement journey until the end of the year. Participants are engaging in a variety of activities, including walking five miles daily in weighted vests, ensuring eight hours of sleep each night, and consuming several liters of water. Many are also deactivating social media accounts to focus on their goals, although some share their progress on platforms like Instagram.

The concept of being “locked in” varies widely among participants. While some aim for financial stability or personal relationships, the overarching theme seems to be a commitment to achieving maximum wellness. On platforms like TikTok, women are sharing journal prompts and setting intentions, while men on X focus on increasing protein intake and eliminating sugar from their diets. A common mantra associated with this movement is “No excuses, just grind,” reflecting a growing culture that prioritizes productivity and self-improvement.

The Great Lock In comes at a time when many are seeking to shift from a summer characterized by indulgence and distractions to a more focused approach as the year concludes. As people contend with economic uncertainties and feelings of isolation, this initiative offers an opportunity for a 121-day journey aimed at personal betterment. It serves as a modern iteration of optimization culture—a movement that encourages individuals to take control of their lives in a chaotic world.

Personal Stories of Commitment

Among those participating is Kadie Glenn, a 28-year-old personal consultant based in London. After experiencing a difficult start to 2025, including a breakup and relocation, Glenn decided to focus on manageable changes rather than an overwhelming overhaul of her life. She has set a goal to run a half marathon in early 2026, beginning with regular runs to build her endurance. “People are wanting to refuel and gain something from 2025 other than what it has been,” Glenn explains. She has also initiated discussions on Instagram to help her followers articulate their goals and support one another.

Research on self-improvement initiatives shows mixed results. According to a YouGov poll from 2020, about a quarter of Americans set New Year’s resolutions, with half maintaining some of their commitments and a third achieving all of them. A study from Sweden indicated that resolutions framed around approaching a goal—like starting a gym routine—are generally more effective than those centered on avoiding negative habits.

Katy Milkman, a professor at the University of Pennsylvania’s Wharton School, highlights the significance of the “fresh start effect.” She notes that new beginnings, whether a birthday or a new year, can prompt individuals to adopt new habits. The Great Lock In, which began to gain momentum in August 2025, embodies this concept, providing a framework for those feeling stuck to initiate change.

Community and Personal Growth

Unlike the rigid 75 Hard challenge, which demands a strict regimen of diet and exercise, the Great Lock In is a grassroots social media phenomenon. It builds upon last year’s Winter Arc initiative that encouraged self-improvement during the colder months. This movement resonates particularly with Generation Z, who seek a more flexible and personal approach to goal-setting amid a landscape filled with distractions.

Wellness content creator Racha Yessouf, 26, is adopting what she calls the “hot girl edition” of the Great Lock In. Her self-imposed rules include waking up at 5 a.m., maintaining a hydration routine, and adhering to a structured beauty regimen. “It’s about focusing on consistency and entering the new year with built-up momentum rather than guilt,” Yessouf states.

Tatiana Forbes, a 31-year-old leadership development coach from Atlanta, has outlined three goals for her participation: decluttering her home, increasing her Instagram following to 100,000, and completing two marathons this fall. Having previously undertaken the 75 Hard challenge, Forbes sees the Great Lock In as an opportunity to reclaim personal power. “This challenge allows you to focus on what you want and filter out the distractions,” she explains.

While online challenges often experience a short-lived popularity, the Great Lock In offers a timely opportunity for individuals committed to making meaningful changes in their lives. As the year draws to a close, participants find a renewed sense of purpose in the quest for self-improvement.
