@marek_kruber_About Me

My name is Marek Kruber, and I am a certified personal trainer.
I'm here to leverage my expertise, backed by 17 years of experience, including my time in Miami, USA. Throughout this journey, I've had the opportunity to work with a diverse range of clients, allowing me to better understand their needs and challenges. My years of practice have taught me that each client is truly unique.
I look forward to working with you and seeing what we can achieve together.
Life around the age of 40 brings many changes and challenges. Between caring for children, managing a career, and handling everyday responsibilities, we often forget about our own needs and desires. This is why women make up the majority of my clientele, as they often struggle with weight issues.

Skvělý trenér, který ví, co dělá, a dokáže člověka správně nasměrovat i povzbudit. Na tréninky chodím s dobrým pocitem a líbí se mi, že nejde jen o samotné cvičení, ale také o správnou techniku, postupné zlepšování a celkový přístup. Oceňuji jeho energii, přístup k lidem a to, že dokáže člověka motivovat i ve chvílích, kdy už mu docházejí síly. Je radost spolupracovat s někým, kdo své práci opravdu rozumí. Za mě velká spokojenost a určitě doporučuji! (Translated by Google) A great trainer who knows what he's doing and can guide and encourage people in the right direction. I go to training sessions with a good feeling and I like that it's not just about the exercise itself, but also about the right technique, gradual improvement and overall approach. I appreciate his energy, approach to people and the fact that he can motivate people even when they're running out of strength. It's a pleasure to work with someone who really understands their job. I'm very satisfied and I definitely recommend him!

S Markem jsem maximálně spokojená! Má skvělý individuální přístup, naslouchá a dokáže trénink přizpůsobit konkrétním potřebám. Velmi oceňuji, že rozumí i ženám v mém věku (50+) a ví, jak s nimi pracovat, aby výsledky byly nejen vidět, ale hlavně cítit. Za tři měsíce spolupráce mám dole 9 kg, přestala mě bolet kolena a celkově se cítím mnohem lépe, fyzicky i psychicky. Marek je profesionál, který svou práci dělá srdcem. Rozhodně doporučuji všem, kteří chtějí něco skutečně změnit! 👍 (Translated by Google) I am extremely satisfied with Mark! He has a great individual approach, listens and can adapt the training to specific needs. I really appreciate that he understands women of my age (50+) and knows how to work with them so that the results are not only visible, but also felt. In three months of cooperation, I have lost 9 kg, my knees have stopped hurting and overall I feel much better, both physically and mentally. Marek is a professional who does his job with his heart. I definitely recommend him to everyone who wants to really change something! 👍

Najít dobrého trenéra není o tom, kdo vám sestaví trénink a jídelák. Je to o člověku, který ví, co dělá, dokáže vás motivovat a přesvědčí vás, že těch posledních pět opakování, kdy už dávno nemůžete, je vlastně upe v pohodě. 😁 Je důsledný, všímá si maličkostí a rozhodně vás nenechá nic odfláknout. Občas mám podezření, že „už nemůžu“ považuje spíš za výzvu než za informaci. 😅 Nejvíc je ale jeho lidský přístup a energie, kterou do své práce vkládá. Za tou horou svalů se totiž skrývá i velké srdce. A to je kombinace, kterou ve fitku nenajdete ❤️ Pokud chcete trenéra, který vás opravdu posune, a zároveň člověka, se kterým je radost trávit čas (tedy alespoň do chvíle, než vám naloží další sérii), Marek je skvělá volba. Doporučuji všemi deseti (po leg day se mě na recenzi neptejte😂). (Translated by Google) Finding a good trainer is not about who will put together your workout and meal plan. It's about someone who knows what they're doing, can motivate you, and convince you that those last five reps you can't do anymore are actually pretty cool. 😁 He's consistent, he notices the little things, and he definitely won't let you get away with anything. Sometimes I suspect that he sees "I can't do it anymore" more as a challenge than as information. 😅 But the most important thing is his human approach and the energy he puts into his work. Behind that mountain of muscles is a big heart. And that's a combination you won't find in a gym ❤️ If you want a trainer who will really push you, and at the same time, someone you'll enjoy spending time with (at least until he loads you up with another set), Marek is a great choice. I recommend it with all ten (don't ask me for a review after leg day😂).

Když jsem si minulý rok na podzim pořizovala nové oblečení na cvičení, nemyslela jsem si, že v něm budu kromě cvičení doma chodit i do posilovny. Jenže když je člověk připraven, učitel se vždy najde a tak na mne začal na instagramu vyskakovat Markův profil…Nejvíc miluju, když mi chce jako ženě nějaký muž vysvětlovat, jak zhubnout. Copak je žena? Využila jsem možnost konzultační hodiny zdarma a šla se na všechno podrobně vyptat. Podvědomě mě lákalo vrátit se po dlouhé době do posilovny, ale neměla jsem sama odvahu. Marek je empatický a sympatický člověk, ačkoli jsem to úplně neměla v úmyslu, dohodli jsme se na spolupráci. Aktuálně spolu cvičíme několikátý měsíc a i když jsem na začátku měla obavy z toho do posilovny vůbec přijít, že na mně “budou všichni divně koukat”, tak jsem nadšená. Myslím, že jsem si z nabídky fitka nemohla vybrat nikoho lepšího. Na Markovi se mi líbí, že se dále vzdělává a svým oborem žije. Kromě trenéra získáte i kamaráda, terapeuta, možnost konzultovat vše. Navíc jeho širokou databázi prověřených lidí z jiných oborů, pokud náhodou potřebujete, protože všechny trénoval, trénuje a nebo bude trénovat (to je vtip, ale celkem pravdivý). Nejlépe investované peníze jsou ty, které investujete do sebe. Jediné, co mě mrzí, že jsem nezačala dříve. Děkuji. (Translated by Google) When I was buying new workout clothes last fall, I didn't think I would wear them to the gym in addition to exercising at home. But when a person is ready, a teacher always comes along, and so Mark's profile started popping up on my Instagram... What I love most is when a man wants to explain to me, as a woman, how to lose weight. Is he a woman? I took advantage of the free consultation and went to ask everything in detail. I was subconsciously tempted to return to the gym after a long time, but I didn't have the courage. Marek is an empathetic and nice person, although I didn't really intend to, we agreed to cooperate. We've been working out together for several months now, and even though I was worried about coming to the gym at all at the beginning, because "everyone would look at me strangely", I'm excited. I don't think I could have chosen anyone better from the gym's offer. What I like about Marko is that he continues to educate himself and lives his profession. In addition to a coach, you also get a friend, a therapist, the opportunity to consult everything. Plus, his wide database of proven people from other fields, if you happen to need it, because he has trained, is training and will train everyone (that's a joke, but quite true). The best money invested is the one you invest in yourself. The only thing I regret is that I didn't start earlier. Thank you.

10/10 – Naprosto skvělý trenér, plná spokojenost! S trenérem cvičím už 8 měsíců a zatím jsem shodila 12 kg ze 17 kg, které jsou mým cílem. Vždy se mnou detailně konzultuje jídelníček a opravdu naslouchá, jak se aktuálně stavím k dietě i cvičení, podle toho mi vždy poradí tak, aby mi to co nejvíc vyhovovalo. Do dnes si pamatuji že jsem se snažila zhubnout ubráním na jídle až jsem skoro už neměla kam ubírat. Postupně až po konzultacích jsem si až uvědomila že se nesmim bát dát pořádné porce. Hlavně ať je strava vyvážená a že z prostého salátu 3x denně se prostě svaly a energie nevyčaruje. 🤭 Naučila jsem se dost o hubnutí, stravě, kalorijích a vše najednou do sebe zapadlo a myšlenka na udržení dietní stravy nebyla tak nemožná. Sama jsem se už mnohokrát pokoušela nastavit si konzistenci, ale vždy to skončilo dříve než začalo. Proto jsem moc ráda, že jsem se rozhodla pro trenéra. Díky němu jsem si vybudovala pravidelný režim a naučila se držet disciplínu i ve dnech, kdy se mi vůbec nechtělo. Vždy má po ruce alternativy cviků, naslouchal co mě baví co prederuji a udržoval tím vždy tréninky zábavné. Jsem víc než spokojená a z celého srdce mohu jen doporučit! Děkuji ☺️ (Translated by Google) 10/10 – Absolutely great trainer, full satisfaction! I have been working out with the trainer for 8 months and so far I have lost 12 kg out of my goal of 17 kg. He always consults with me in detail about the diet and really listens to my current attitude towards diet and exercise, and accordingly, he always advises me in a way that suits me best. To this day, I remember that I tried to lose weight by cutting back on food until I almost had nowhere to go. Gradually, only after the consultations did I realize that I should not be afraid to eat big portions. The main thing is that the diet is balanced and that a simple salad 3 times a day does not simply conjure up muscles and energy. 🤭 I learned a lot about weight loss, diet, calories and everything suddenly fell into place and the idea of maintaining a diet was not so impossible. I have tried many times to set a consistency for myself, but it always ended before it started. That's why I'm so glad I decided to have a trainer. Thanks to him, I built a regular routine and learned to stay disciplined even on days when I didn't feel like it. He always has exercise alternatives at hand, he listens to what I enjoy and what I'm struggling with, and he always keeps the workouts fun. I'm more than satisfied and I can only recommend him with all my heart! Thank you ☺️

Extrémně zkušený trenér, neustále se vzdělává v oboru. Netlačí univerzální recepty, ale vždy hledá funkční řešení na míru. Poradí se cvičením, celkovou životosprávou i různými zdravotními problémy. Výsledky jsou cítit a vidět. (Translated by Google) Extremely experienced trainer, constantly educating himself in the field.
