About

I help women understand why their body adapted — and what to do next.

I am Alejandra Belmar — Chilean-born, Brooklyn-based, a Functional Medicine Health Coach, strength trainer, and human adaptation specialist for women 40+.

For more than twenty years, I have worked with women through perimenopause, menopause, postnatal recovery, injury, chronic pain, and the long process of finding their way back to strength. For many years I called myself a trainer because it was the word people understood. But training is only one part of what I do.

What I actually do

I look at how your body has organized itself around everything it has lived through.

Hormonal change, stress, injury, surgery, pain, caregiving, disrupted sleep, work, and the movement patterns repeated over years. Then I help you notice what your body is doing and introduce new information through strength, breath, movement, sensory input, fascia work, and recovery. We reassess as we go. Your response tells us what matters.

Sometimes a change at the foot alters what the opposite shoulder can do. Sometimes sleep or nourishment is limiting the training more than motivation. My job is not to force your body into a formula. It is to pay attention well enough to find the next useful step.

Why I created Antu Mar

A place where the pieces can finally speak to one another.

Women are often given separate pieces: a workout, a prescription, a physical-therapy exercise, a supplement, a breathing practice. Each may be useful, but no one helps them understand how the pieces speak to one another — or which one matters now.

I created Antu Mar to give this work a home: a place where strength, nervous-system health, hormonal transition, recovery, and lived experience can be held in the same conversation. Antu Mar is not a method separate from me. It is the place where you meet my work, learn to understand your body, and build strength with support.

What I promise

Four commitments.

I will look at the whole.

I will not reduce you to one symptom, one joint, one lab value, or one stage of life.

ii.

I will treat your experience as information.

You live in your body every day. What you notice matters. I bring education, pattern recognition, and a framework; we work in partnership.

iii.

I will be honest about my scope.

I coach, assess movement, teach, and help you organize the daily practices that support your health. I do not diagnose or replace your physician, physical therapist, or mental-health provider. When something needs medical attention, I will tell you.

iv.

I will hold the long view.

We are not chasing a smaller body or a four-week transformation. We are building strength, skill, and capacity you can continue using as your life changes.

Antu — Mapudungun

The word for sun.

Antu is the Mapudungun word for sun. Mar is the Spanish word for sea. The name holds my Chilean inheritance — Mapuche and Hispanic — and the meeting of two languages and two ways of knowing.

Mar — Spanish

The word for sea.

My surname, Belmar, means beautiful sea. Antu Mar is personal: sun and sea, strength and change, where I come from and what I am building next.
