Breathe
On land, sitting or lying down, eyes open. Slow breaths that settle you before the water. Never a breath-hold near the tub.

Cold-plunge coaching · Miami
One coach, a 4 °C plunge and a 90 °C sauna. The 4·90 method takes you from your first cold shower to three calm minutes in the plunge, with someone beside you the whole way.

The honest part
You’ve watched the videos. Someone in a frozen lake, a countdown, forty more in the sidebar. Then you stand over a tub of ice at home and nobody tells you what to do with the first ten seconds. That’s not a willpower problem. It’s a coaching problem.

Coached, with Maren
ISVAK · Week 2
Saturday, 7:00 am
The video doesn’t know your name. Maren does.
Meet your coach
Maren grew up taking winter swims in Sweden, then moved to Miami, where the ocean sits near 28 °C and the cold has to be made on purpose. She coaches beginners: people who are curious, a little scared, and tired of doing it alone.
Her rule: calm first, cold second. Every session starts on land, slow and unhurried, and nobody gets in before they’re ready.
The 4·90 method
4 °C to 90 °C, in the same order every time, so your body knows what’s coming.
On land, sitting or lying down, eyes open. Slow breaths that settle you before the water. Never a breath-hold near the tub.
Shoulders under, hands out if you need them. Maren counts you through the first ten seconds; the rest is yours.
Into the sauna at 90 °C, then rest. Warm up on your own terms, never in a rush.
The 4·90 Program · 6 weeks
Live group sessions every week, a weekly check-in with Maren, and a plan that only ever asks for the next small step.
The last 30 seconds of your shower, cold.
Breathing practice on land each day, and your first live group session. No tub yet.
Coached, at 10 °C, for as long as it feels calm.
Aim for 30 to 60 seconds. Then the sauna, then rest.
Down to 6 °C, up to 90 seconds.
Your first full heat round: plunge, sauna, rest.
Three rounds of cold and heat, with rest between.
Maren times the sauna so you finish warm and steady.
Two minutes at 4 °C, and a plan for home.
Cold showers or a tub at home: we set up what fits your space and your schedule.
Three calm minutes at 4 °C, then a full heat routine.
You leave with a routine you can run without us.
Student notes
Sample notes: invented people for this demo, not real reviews.
I’d watched forty videos and never got in. Week two, I did a full minute and laughed out loud.
The Sunday check-in kept me going. Someone noticed when I skipped.
I still hate the first ten seconds. Now I know what to do with them.

Safety, plainly
Nothing here is extreme. These three rules hold for every session.
All breathing practice happens on land, sitting or lying down. In the tub, you just breathe slowly.
Especially with a heart condition, high or low blood pressure, or if you’re pregnant.
Your first plunges are guided. Later, at home, never plunge alone.
Questions
Yes. The program is built for people who hate it. You go at your own pace, start with a cold shower, and nobody pushes you past calm.
About ten minutes at home: a short breathing practice on land and a cold finish to your shower. Group sessions are once a week.
No. Your shower is enough to start, and the plunges happen with us. In week 5 we look at home options together, from a simple tub to sticking with showers.
Swimwear, a towel and warm clothes for after. Robes and water are on us.
