For women navigating perimenopause, menopause, and the years that follow — strength training that meets you where you are, respects what your body is doing, and builds toward what you want it to do for decades.
Programming designed for what your hormones are actually doing — not generic strength training adapted for women. The right load, in the right order, for where you are right now.
You know your body better than anyone. We bring the science, the experience, and the framework. You bring everything you already know about yourself. We move forward together.
The strength you build now is the foundation for fifty, sixty, seventy. We are not interested in shrinking you. We are interested in what you are capable of becoming.
Thread by thread. Season by season. Every part holding the next.
When you train this way, you'll find your bones get stronger and your sleep gets deeper. Your energy stops disappearing in the afternoon. The aches you have learned to live with get quieter. You will move through your weeks with more capacity, not less. This is what hormone-intelligent strength training does — when it's built around the woman you actually are, not the woman a magazine says you should be.
Read the method →Most women begin in our small-group coaching — the most welcoming way in. Some begin one-on-one. Whichever way you choose, you'll be doing this with women who get it, and with a coach who is paying attention to you.
Multiple live training sessions every week. Monthly group clinics where you ask the questions you can't ask anywhere else. Recordings of every session for the weeks life gets in the way. A small community of women in the same chapter as you. Direct access between sessions for what comes up.
For women ready to start — and ready to stop doing this alone.
Learn about Group Membership →Working one-on-one is the most direct path through this chapter — programming designed for the body you actually have, the hormonal stage you are in, the schedule you live. You will sleep better. You will move with more strength. You will have an expert in your corner between sessions, and you will join the small group sessions when you want the company of other women in this work.
For women who want depth and attention — and who are ready to do the work.
Inquire about Private Coaching →If you are tired of being your own care coordinator — the doctor who renewed the prescription but doesn't know what you're lifting on Tuesdays, the trainer who doesn't know what your hormones are doing, the supplement aisle that's a black hole — we are building Coordinated Care for you. The next step beyond Group Membership, with your hormone care held in the same hands as your training.
Join the Coordinated Care waitlist →Two or three days away — to learn this work in your body, surrounded by women in the same chapter as you, in a place built for quiet. You will leave knowing how to train. You will leave knowing what your body actually needs. Our first Weekend Retreat is in development for early 2027 — a single pilot, sized small, in a place chosen with care.
Notify me when announced →More is coming — Small Group Coaching (small-cohort coaching), Online Courses (self-paced courses), Workshops (workshops), and Flagship Retreat (the multi-day flagship). Each one will open when we can deliver everything you deserve. Subscribe to Diario and we'll let you know when each opens to you.
A Chilean coach and methodologist who refused to accept what generic fitness was offering women her age — and built something better instead.
For more than twenty years, Alejandra has worked one woman at a time — through perimenopause, through menopause, through postnatal recovery, through the long arc that follows. What she now teaches as Antu Mar is the result of those years, distilled and made teachable. Her surname — bel mar, beautiful sea — and her cultural inheritance from both Mapuche and Hispanic Chile run through everything she builds for the women who come to her.

We are not anti-aging. We are pro-strength — at forty, fifty, sixty, seventy. The body you are living in is not a problem to be solved. It is the foundation you are building on. — Alejandra Belmar
