Bring Someone Worth Training With.

We don’t just want more members.
We want more people like you.

The attitude. The work ethic. The consistency.
That’s what built Black Flag, and that’s what we stand for.

So if you’ve got a friend, family member, or significant other who moves like you, thinks like you, and is ready to actually train…

Bring them in.

Because training with the right person doesn’t just make it easier
it makes you better.
More accountable. More consistent.

Here’s the deal:

• Your person gets 2 FREE weeks of small group classes
OR
• They can join you for a full week of personal training

No gimmicks. No pressure.
Just a chance to see if they belong here.

If they’re built like you…
they probably do.

Tired of “small group” classes that aren’t actually small?

How many times have you left your “small group” class having no idea how to do the exercises correctly, or why you did those exercises?

A class advertised as small group training…
But when you show up there are 15–20 people in the room, the coaches “instruction” comes in the form of vague motivational jargon, and half the time you are wondering if you are doing the exercises correctly…

No coaching.
No form correction.
No attention to mechanics.

That’s not coaching. That’s generic corporate fitness designed to maximize profits, not designed to help you really understand movement and your body.

At Black Flag Gym, small group means what it says.

Our sessions are intentionally limited so coaches can actually watch your movement, correct your form, and help you improve every rep.
You get the energy of a group setting with real instruction and accountability, not just a timer and a playlist.

Because if no one is coaching your biomechanics…
you’re not really being coached.

If you’re ready to experience what true small group training feels like, come see the difference.

Tired of “small group” classes that aren’t actually small?

You’ve seen it before.

A class advertised as small group training…
But when you show up there are 10-15 people in a cramped room, the coach tells you to follow the workout on the board and then yells some motivational mumbo jumbo at the group.

No coaching.
No form correction.
No attention to mechanics.

That’s not coaching. That’s generic corporate fitness designed for profits, not for you to actually learn and understand your body.

At Black Flag Gym, small group means what it says.

Our sessions are intentionally limited so coaches can actually watch your movement, correct your form, and help you improve every rep.
You get the energy of a group setting with real instruction and accountability. Not just a timer and a playlist.
