After a stint as a headhunter and management trainee at the alcoholic beverage company Pernod Ricard, Wong joined Lululemon Athletica, where she worked in the social media division.

Her exercise videos received the most views, and she grew into an influencer in the realms of fashion, beauty, lifestyle, and fitness.

Emily Wong was born in January 1992 in Toronto, Ontario, and moved as a baby to Hong Kong, where she was raised.

[11] In her first job after graduating from university at the alcoholic beverages company Pernod Ricard, Wong worked as a headhunter, a role she did not like because it required a salesperson personality that she felt she lacked.

[14] She later joined the Hong Kong branch of Lululemon Athletica, where she worked in the social media division for two years until around August 2018.

When Chad, her boyfriend, questioned her, Wong admitted that her inordinate time in the bathroom was owing to her affliction with bulimia.

[11] With increased responsibilities but a lack of appreciation given for her work, Wong found her full-time job to be unsatisfying and could not envision doing it long-term.

Unable to allot sufficient time to being a personal trainer, she considered becoming a YouTuber after a friend told her how it was an opportunity to make money and a coworker supported the idea.

[7][17] Wong's first video was in English to accommodate her boyfriend, whose English-language skills were superior to his Cantonese-language proficiency, because she was nervous and hoped to have someone else join her.

[2] Within one year of creating the channel, she received 500,000 subscribers which prompted her to resign from her social media role to become a full-time YouTuber in August 2018.

[18][7] Wong had attended events from brands including some held overseas which required taking time off from work.

In a 2020 interview with the South China Morning Post, Wong attributed her channel's success to how the workouts could be completed at people's residences.

She said that the videos, which lasted between 10 and 20 minutes long, could be done by people who lacked the time or money to pay daily visits to the gym.

[26] At the beginning of the COVID-19 pandemic in early 2020, she posted a video where she used a carpet sweeper to do lunges and bottles of laundry detergent to do squats.

Telling her viewers that sanitising and working out are compatible, she added a caption to the view that said "Keep both hygiene and immune system up".

Au further criticised Wong's movement that she called "arm chest expansion", which the reporter found "increases the chance of shoulder joint strain" by "failing to maintain stability".

[24] Wong lives at Villa Lucca (Chinese: 林海山城), a luxury residential development, in Ting Kok, Tai Po District, in the New Territories region of Hong Kong.
