You’ll notice a change if you walk into any mid-size gym on a Tuesday night. Twenty-two-year-olds are filming their sets, adjusting their grip, and checking their macros in between reps in the free weights section, which used to be the exclusive domain of men in their thirties who grunted at each other over deadlifts. It’s more than just a shift in mood. It is supported by the numbers. Since 2020, Gen Z memberships in gyms have almost doubled, accounting for 29% of all new memberships. This generation is actively pursuing whatever it is that they are interested in.
It’s a flattering surface reading. On paper, public health officials envision a generation that prioritizes physical health, abstains from alcohol, and gets up early to train. This generation may become “the most health-aware generation ever,” according to the chief executive of UKActive. This claim is made so frequently that it begins to sound like a press release. The reality beneath is messier, more fascinating, and, to be honest, a little more difficult to fully embrace.

Anxiety about appearance, productivity, and keeping up is a major factor driving young people into gyms, rather than health. Almost half of Gen Zers claim that their main motivation for working out is to look better. According to 40% of respondents, social media actually causes them to feel self-conscious about their appearance. There’s a difference between training. You’ve spent twenty minutes watching someone else’s transformation video at midnight and training because your body feels good when you move. Although both may be occurring simultaneously, it’s important to keep that distinction in mind.
All of this is further complicated by the Hyrox phenomenon. What began as a specialized fitness competition that combined functional exercise and running has grown into something more akin to a way of life. Competitors spend up to £1,000 on a single competition weekend, travel abroad for events, purchase matching team uniforms from luxury brands, and share finish-line pictures that conflate social media content with athletic accomplishment. A London-based gym founder invested £75,000 to create a custom Hyrox training area. It’s still unclear if this is the epitome of community-driven fitness culture or if it’s just an expensive manifestation of the same appearance anxiety wrapped in compression shorts.
The notion of exercise as an incidental activity, such as going for a walk with a friend or engaging in a lighthearted game while doing something else, appears to be disappearing. The gym is intended to be a solitary, independent area. Headphones in, eyes forward, mirrors everywhere. It is nearly allergic to spontaneity and optimized for self-improvement. Observing how many members of this generation are drawn to it, it seems that the appeal lies not only in fitness but also in a sense of control. How many sets you performed on Tuesday is the only thing you can control when housing costs are exorbitant, job markets are unstable, and the future seems genuinely unclear.
Despite its mess and expense, the pub offered something unique. By design, it was an ineffective place to squander time together, which is a worthwhile activity. The economy doesn’t help the steady rate of pub closures. These days, a pint in London usually costs more than six pounds. The math for a twenty-something with limited funds is clear when compared to a £28 monthly gym membership. This generation is likely too preoccupied with training to consider whether what takes the place of those evenings is truly superior in ways that go beyond the measurable.
