A home gym · run by hand
A private home gym run by Lars Thestrup & Barry Diner. Serious equipment, personal coaching, and a community that knows your name.
Why we built this
Most gyms are loud, crowded, and impersonal. We wanted the opposite. Jane Street Gym is a home gym turned into a real place to train — small enough that everyone knows your name, equipped well enough that you never have to wait for a rack. Come for the weights, stay for the people.
The space
Everything you need to train hard, nothing you don't. Here's a look at the gym — we'll show you the rest in person.
