Cannot you just go to random gym, pay for enterance and do ya thing without signing stuff?
There's only a few types of gyms where most of the members actually use the gym, and although they're still subscription based, they have entirely different business models.
He left and is now working for a company that actually wants its customers to use its product more.
"Pizza Fridays!"
"Judgement free zone!"
"No lunks in here! Lunk alarm!"
They know the demographic they are shooting for.
Most gyms I've been to do not allow local residents to purchase 1-day passes.
They do often allow people visiting (on business etc.) to purchase a daily or weekly pass. But may need your ID to prove that, and you can only do that so many times. Like if you visit for two weeks once a year they're happy to. If you come once a month for business, you're gonna need a full membership.
And you've always gotta sign stuff no matter what. For liability, so they know who to contact if you keel over on the treadmill, and so forth.
The alternative I've commonly seen is they do offer a day pass, but it's basically the cost of an entire month to go even one time, while also making it extremely inconvenient by having to sign a bunch of forms every single time you go. This makes it so nobody except maybe a tourist/non-local would ever consider this option.
In eastern eu I just enter the gym and purchase daily or monthly ticket
Just like train ticket
