Starting training after 40 in Koszalin
Starting to train in your forties after moving to Poland: how the Polish health checks work, which blood tests you can order yourself without a referral, and what genuinely changes with age.

Note: This article is informational and educational. It does not replace medical advice or a physiotherapy consultation. If you have a chronic condition, joint pain, chest symptoms or a family history of heart disease, speak to a doctor before you start a new programme.
You are somewhere in your forties, you have landed in Koszalin for work or study, and you have decided this is the year you start training properly. Then someone tells you to get checked first, and it turns out you have no idea how that works here. You are not registered with a doctor. You are not sure what your insurance covers. And you do not want to lose a month to paperwork before your first squat.
The short version: you may already have more medical data than you think. If you work for a Polish employer, they have paid for a health check you were legally obliged to attend, and you can ask the clinic for the results. If you have no employer here, Polish private labs take walk-ins for the basic blood panel — no referral, no appointment, results online within a day or two. Either way, the check runs alongside your first weeks of training, not instead of them.
First, drop the metabolism story
You have been told that the body slows down after forty and that this is why the weight creeps on. The largest study of human energy expenditure ever run says otherwise. Pontzer et al., Science 2021 measured more than 6,400 people, from infancy to age 95, using doubly labelled water — the reference method, where you drink water with tagged hydrogen and oxygen and researchers track how fast your body clears it. Adjust expenditure for fat-free mass and it holds steady from 20 to 60. The decline starts far later than most people assume.
That changes what you do about it. If your metabolism has not slowed, the change in the mirror has another cause: you carry less muscle and you move less across the day. Both of those you can act on. A “slow metabolism” you cannot. So the answer here is not a diet. It is putting muscle back on and getting your daily step count up off the floor.
Getting checked, the Polish way
This is the part no Polish guide bothers to explain, because every Pole grew up with it.
Medycyna pracy — the check you may already have had
Medycyna pracy is occupational medicine, and in Poland it is not optional. Before you started your job, your employer sent you to a doctor licensed to carry out occupational assessments, handed you a skierowanie (a referral) and paid the bill. That was your badania wstępne, the pre-employment examination. It repeats on a fixed schedule as badania okresowe, the periodic checks, for as long as you hold the job.
Newcomers miss two things here. The first is that the piece of paper you were given — the orzeczenie lekarskie — only states that you are fit for the role. It is not your results. The second is that the results themselves exist, and the clinic will hand over a copy if you ask for one. Depending on the job that can include blood pressure, a blood count, sometimes an ECG and a vision test. The request is one sentence: Proszę o kopię wyników badań — please give me a copy of my test results. One phone call is worth making before you pay for anything privately.
The limits are real, though. The scope is set by the hazards of your job, so a desk role gets a thin panel, and the certificate judges you fit for that work — not for deadlifts. And if you are a student, a freelancer or on a foreign contract, this route does not exist for you at all.
Registering with a lekarz rodzinny
Your GP here is the lekarz rodzinny, also called the lekarz POZ — POZ stands for podstawowa opieka zdrowotna, primary healthcare. You reach one through a przychodnia, the neighbourhood clinic, and you have to sign up actively: you fill in a deklaracja wyboru, a short form naming that doctor as yours. Bring your PESEL, the national identification number issued to residents. It costs nothing and takes a few minutes at the reception desk, and the sentence to walk in with is Chcę złożyć deklarację wyboru lekarza POZ — I would like to register with a primary care doctor.
You can move to a different practice later. There is a cap on how many free changes you get in a year, and past that you pay for the switch.
Do this even if you feel fine. Without a registered lekarz POZ, publicly funded tests and referrals are not available to you.
NFZ or private
Public healthcare runs through the NFZ — Narodowy Fundusz Zdrowia, the national health fund, paid for by health contributions taken out of wages. If you are insured through it, a visit to your registered lekarz POZ and the tests they order cost you nothing. What you trade is time: appointments are not always same-week, and the doctor decides which tests are justified.
Private care is the other lane. You book online, you are seen within days, and you pay per visit. If you are here on an EHIC card from another EU country, read what it actually covers: treatment that becomes necessary during your stay, not a routine fitness screen you have decided to arrange for yourself.
The four checks worth having before you load a barbell
You do not need a doctor for most of this. Polish private laboratories take walk-ins without a referral — Czy mogę zrobić badania bez skierowania? means “can I do the tests without a referral?”, and at a private lab the answer is yes. We have not checked current lab prices in Koszalin and they differ from provider to provider, so read the price list on the lab’s own site rather than trusting a figure from us.
- Morfologia — a full blood count. The broadest cheap screen there is.
- Lipidogram — the cholesterol panel: total, LDL, HDL, triglycerides.
- Glukoza na czczo — fasting glucose. It matters most if you are carrying extra weight; we cover what comes next in insulin resistance and training in Poland.
- Ciśnienie — blood pressure. Not a lab test at all: many pharmacies will measure it for you free of charge, and it is the single most useful number on this list.
For the lipid panel and the glucose you go na czczo, fasting, so book a morning slot at a punkt pobrań — a sample collection point — and eat afterwards. Results usually land online within a day or two.
One limit on all of it. Blood tests you ordered yourself are a starting point, not a clearance. Chest pain on exertion, blackouts, an irregular pulse or a strong family history of heart disease mean you see a doctor before you see a trainer.
What actually changes after 40
Muscle loss is the real change. Without resistance training, muscle mass and strength fall away from the fourth decade onwards, and the rate picks up with age. That is what sits behind the shift in body composition people blame on metabolism. It also responds unusually well to work: people who start lifting in their forties tend to add strength fast over the first months, precisely because they begin from an untrained baseline.
Recovery genuinely takes longer. Soreness that cleared overnight at 25 can run 48 to 72 hours at 45. Hormonal shifts — testosterone in men, oestrogen in women through perimenopause and menopause — affect how quickly you build muscle and how well you hold bone density. Cartilage wears down, so knees, hips and the lower back complain more often. None of that argues for sitting still. Movement is what keeps the joints working.
How to train, in four lines
Strength work is the foundation, not the extra. Two or three sessions a week is enough to change things. Squats, deadlifts, rows, pressing overhead and horizontally, hip thrusts. The load should be demanding without forcing you through a painful joint, and finding that line is the main thing a good coach is selling you.
Mobility is not optional. Ten to fifteen minutes after every session, aimed at the hips, the chest and the thoracic spine — the middle of your back, behind the ribs. Years at a desk stiffen exactly those three.
Recovery is part of the plan. Three or four good sessions a week beat six mediocre ones. Sleep seven to nine hours. Protein matters more now than it did at 25: aim for at least 1.6 g per kilogram of bodyweight a day. Shopping for that here is easier than you would guess — see eating for training from a Polish supermarket.
Learn the difference between sore and injured. Muscle soreness is diffuse and dull, arrives 24 to 48 hours later and eases once you move. Joint pain is sharp, points to one spot, and shows up during the movement itself. The second kind gets looked at. In Koszalin, the sports physiotherapists who work alongside trainers include Katarzyna Kaczmarz and Filip Bielecki (Inferno Gym, ul. Bohaterów Warszawy 2A) and Katarzyna Ejsmont (MoveLife, ul. Rekreacyjna 14). Ul. is short for ulica, street, so the first of those addresses is number 2A on Bohaterów Warszawy Street.
Starting in Koszalin
Prices here are quoted in złoty, written zł on a door and PLN online, at a rate near 4.3 zł to the euro. A single gym entry at MyGym costs 39 zł (about 9 EUR) and a 14-day pass 129 zł (about 30 EUR). One-to-one coaching sits higher: Aleksandra Zwolak, who works out of the Siłownia 16 gym — siłownia is simply the Polish word for gym — publishes 140 zł (about 33 EUR) per session. Most trainers here publish nothing at all and settle on a rate at a first meeting, and that meeting is normally free. The full breakdown of costs and how paying works covers passes, packages and employer sports cards.
When you make contact, ask two things. Ask directly about experience with people who start in their forties: a coach whose week is built around competitive twenty-year-olds is a poor fit even if they are excellent. Then ask whether they are able to work with you in English. We hold no record of who can, so we are not going to promise it on anyone’s behalf; some coaches here have studied or competed abroad, and asking is the only reliable way to find out. For both questions, a written message works better than a phone call.
If a joint or an old injury is the reason you have been putting this off, look at what a trener medyczny does before you book anyone else. Otherwise, start with the trainer directory, and read what your first weeks in a Polish gym look like so the reception desk holds no surprises.
The order that works: register with a lekarz POZ this week, ask your employer’s clinic for the results they already hold, book the blood panel for a morning when you can skip breakfast — and start training on Monday regardless. Waiting for a clean bill of health before the first session is how people spend a year not training.
