Introduction

Soniya Singh Khatri is not just a fitness influencer, she is one of India’s most recognisable faces in the health and wellness digital space. At a time when most fitness content on Indian social media was dominated by male trainers only, Soniya carved out her own space by being strong, practical, and real.

Her content does not sell fantasy. It sells discipline. She shows her actual workouts, actual meals, actual rest days, and that honesty is exactly what has kept millions of followers glued to her page year after year.

But behind the reels and the impressive physique is a woman who started from scratch, survived a platform ban that killed most of her peers’ careers, transformed her own body through years of trial and mistakes, and built a gym business from the ground up alongside her husband. This biography tells that full story.

Early Life and Background

Sonia Singh Khatri was born on August 12, 1995, into a middle-class family in Delhi, India. Growing up in Delhi, Sonia developed a keen interest in physical fitness from a young age. It was a passion that began as a purely personal but eventually it made her entire career.

Her family was not come from any fitness or entertainment industries, nor did her parents come from a wealthy background. Her father ran a small-scale business, while her mother managed the household. Despite this traditional background, Sonia has always been inclined towards gym culture, healthy eating and maintaining an active lifestyle.

During her teenage and young age in Delhi, she began taking her workouts seriously and discovered something that would later become a key part of her brand identity. Fitness truly transformed not only her body, but also her confidence, mental health, and daily energy levels. She wanted to share this experience with others, and social media became a great platform for her to do just that.

Education

Sonia completed her schooling in Delhi and graduated from Delhi University. While the name of her college or university isn’t publicly available, she holds a graduate degree.

Unlike many content creators who drop out or avoid education, Sonia completed her studies before fully committing to her content career. Her educational background, while not in fitness or media, provided her with a foundation that’s evident in how professionally she’s managed her brand and business partnerships over the years.

Career Beginnings

Sonia Singh Khatri started uploading videos to TikTok around 2018, when it launched in India. Initially, she created a mix of lip-sync, dance, and fitness content. That’s when she created her handle, @fitgirl_08. She chose this name to represent her identity and hasn’t changed it on any platform since.

Her videos started going viral, and people started connecting with her from the initial days. Her workout clips stood out because they felt real. No fancy studio, no heavy editing, just a girl working hard in the gym and sharing her videos on TikTok.

Then came June 2020, and the Indian government banned TikTok along with 58 other Chinese apps. For most TikTok creators in India, it was a terrible time. Overnight, their platform, their audience, and their income vanished.

Rise to Fame

When TikTok was banned, Sonia immediately began creating videos on Instagram and YouTube. Her Instagram account, @fitgirl_08, became her main account, and she began posting workout reels, nutrition tips, gym routines, and motivational content, similar to what she had done on TikTok.

At the time, the Indian fitness community on Instagram was dominated by male creators, with no female creators making fitness videos, and Sonia filled that gap perfectly. Her content stood out for several reasons:

She showcased real workouts, not just aesthetics.

She spoke honestly about nutrition, including what she actually ate.

She openly shared her personal transformation story.

She posted consistently, which sent strong signals to the algorithm.

Her follower count continued to grow rapidly throughout 2020 and 2021, and then increased even more rapidly with the launch of Instagram Reels in India. By 2023, her Instagram followers had crossed 2 million. By 2026, her followers had reached 3+ million, making her one of India’s most followed fitness creators.

She created her personal YouTube channel, @fitgirl_419, in January 2023, where she began uploading detailed workout tutorials, health tips, and lifestyle vlogs. Since then, the channel has garnered a total of 173 million views, a significant number for a channel launched just a few years ago.

Controversy

Shooting incident near RK Fitness Gym (2026)

In January 2026, Sonia Singh Khatri and her husband, Rohit Khatri, became the subject of national news coverage after a shooting incident occurred at or near their gym in Delhi. Investigators revealed that two of the accused were in contact with the Lawrence Bishnoi gang through social media, and were allegedly being guided by handlers working abroad via encrypted messaging apps.

Delhi Police confirmed that both Rohit Khatri and his team were safe after the incident, and security was significantly tightened in the area. Both accused were arrested within a few days.

Neither Sonia nor Rohit made any public statements on their social media immediately following the incident.

As of March 2026, both are active on their social media platforms, and RK Fitness remains fully operational at all of its locations in Delhi. This incident was not directly caused by any action by Sonia or Rohit and they were victims in the situation, not involved in it.

She loves travelling and regularly shares travel content alongside her fitness posts.

Conclusion

Sonia Singh Khatri’s journey is a story of innovative thinking, courage, and hard work. She didn’t have a celebrity launch, nor does she come from a famous family background. She built her brand through daily gym sessions, consistent content posting, and the courage to keep going even after a platform ban robbed her career of its initial momentum.

Today, @fitgirl_08 isn’t just a handle, it’s a brand and a business. From a Delhi girl who loved the gym to one of India’s fitness voices, Sonia Singh Khatri has proven that consistency, hard work, and a little science can truly take you far.
