Perfect 7 day gym split:

The video likely resonated due to its relatable and humorous take on gym culture, specifically targeting the common trope of friends who prioritize social activities like going to the pub over strict workout routines. The simple, repetitive structure and unexpected inclusion of 'Pub' as a workout day make it easily shareable and memorable.

The video humorously outlines a "perfect" 7-day gym split, which consists of alternating "Push" and "Pull" days with "Pub" days, and concludes with a "Chill" day. It's presented in a parody style, suggesting this is the kind of split a certain type of friend might follow.
