We’ve been trying to wrap our head around this since we heard the heartbreaking news last week,
and wanted to share here.

We’ve lost one of our own: Zach Attack.
His life tribute in the SF Chronicle spoke beautifully about his background and family, but he had another family: us.

He came to me with a clear goal I’ll never forget: “I want to feel like a bad-ass 50 year old.”

He quickly fell into sync with the koimmunity, cracking jokes, challenging himself and encouraging others on the trails. He didn’t just show up for the workout he showed up for us too. He connected with many of us through laughter, shared stories, and those small but meaningful moments that stick with you forever.

Never short on smiles, he was with us for many brunches, a handful of holiday celebrations, bowling nights, countless morning baker beach workouts and so many memories in between. I really enjoyed him while he was with us, and he will be deeply missed.

To our koi family - please know we are here for anything you need. Let’s lean on one another.

We love you, Zach Attack. We’ll see you at the top of the sand ladder.

-Stevan and the Koi Fitness Team 🤍
