What to Expect
No intimidation. No guesswork. Just real progress — at a pace that works for you.
From your very first session, you'll know you're in the right place. Our coaches take the time to understand where you are, what your goals are, and what's gotten in the way before. Then we build from there — with a clear plan, intentional programming, and the kind of coaching that keeps you accountable without making you dread walking through the door.
Every session is structured, coach-led, and designed to fit into a busy life. You don't need a fitness background. You don't need to already be in shape. You just need to show up — and we'll handle the rest.
Training at ANNEX means you're never left to figure it out alone. Our coaches are with you every step of the way, adjusting when life gets busy, pushing when you're ready for more, and always keeping your long-term health at the center of everything we do.
