Benefits

Visible results in 12 weeks

Our Weight Loss & Muscle Mass Program transforms your body through smart training and sustainable habits.

Here’s how we help you succeed:

Fat loss that lasts

Our sessions centre on strength, because more muscle means a faster burn, even at rest. Each workout builds lean tissue and keeps your metabolism running hotter for hours. We track your body‑fat and celebrate every drop together. No guessing, no pills. Just clear effort and clear proof.

Progressive weights wake sleepy muscles. As muscle grows, your shape tightens and your metabolism climbs. Your coach teaches perfect form and nudges the weight up only when you’re ready. Logging every milestone so you see steady gains in strength and confidence.

Better food, better sleep, better mood. We swap crash diets for balanced meals you enjoy, add mini mobility drills to ease tension, and build a bedtime wind‑down that actually works. The payoff: sharp focus at work, patience at home, and the spark to enjoy your evenings instead of crashing on the couch.

Paar weken getraind met Ender, en dat is uitstekend bevallen. De sportschool heeft alle faciliteiten die je zoekt en Ender is een super fijne pt: hij is deskundig, kan die deskundigheid vertalen naar gewonemensentaal en hij is ook nog eens vriendelijk.

Heel tevreden over B-One! Het is er schoon, netjes en er hangt een hele prettige sfeer. Iedereen is ontzettend vriendelijk. Ik train hier nu 4 maanden. De uitgebreide intake vond ik erg prettig. Er wordt echt de tijd genomen om je doelen, wensen en situatie goed in kaart te brengen. Mijn PT Saskia begeleidt me hierbij fantastisch! Ik ben relatief nieuw met krachttraining, en ze besteedt veel aandacht aan goed aanleren van de technieken en houdt mijn persoonlijke progressie duidelijk bij, waardoor dat heel goed zichtbaar is. Verder krijg ik goede ondersteuning rondom voeding en leefstijl. Al met al een zeer fijne, professionele plek waar ik inmiddels met veel plezier train!

I've been training with Saskia for 4 months now at B-One at the Zuid location, and I cannot recommend her and the studio enough. The studio itself has a calm, warm, and welcoming atmosphere that makes you feel comfortable the moment you walk through the door. What truly sets this place apart is the personal attention and care you receive. Saskia has been absolutely wonderful - she pays close and careful attention to my form and individual needs, ensuring I am working out safely while still finding ways to challenge me. Having this routine has allowed me to feel so much stronger and confidently push myself, all while feeling properly looked after. I love this place so much that I actually convinced my mom to join—so if that doesn't say 'highly recommended,' I don't know what does ;)

We’ve been training with Stef for over a year now, and he has genuinely made our sessions something I look forward to every week. I quickly noticed how much of a difference there was between training on my own and training with Stef — I’ve made progress much faster, while also feeling much safer and more confident in what I’m doing. Beyond the training itself, Stef is excellent to work with. His communication and attitude strike exactly the right balance between professional and friendly, and he always creates a positive atmosphere. I honestly don’t think we could have found a better PT. Super happy with the results, and even happier to have gotten to know him.

B-One is incredible and I cannot recommend them enough. The facility is clean and welcoming. The trainers are smart and professional. The intake process is well thought out and effective. And the environment is so welcoming and kind, it manages to make even working out fun. Working with both Rufus and Yulia, I have nothing but positive things to say about them both. They are thoughtful, give well reasoned advice and answers to my questions, and are very considerate of not only helping me meet my goals but giving me a foundation of knowledge so that I understand what works and why. Working with B-One for a few months, I’ve been injury free longer and seen more results than any other period of working out in my life.

I only did 6 sessions so far, but really enjoying the experience. It’s the first time training and I feel very at ease with Yulia. My training and muscles are growing, and she makes sure I have the right posture and exercises so my recovery time is super fast. I really like the place, everyone is very friendly and it’s never too crowded and love the complimentary protein shake. I always leave feeling energised and this motivated me to become more active during the week. Moreover, I am already seeing some progress whilst learning about the exercises and what my body needs.

Wij sporten nu 2,5 maand bij Saskia van B one en zijn super enthousiast! Ze is eerst teruggegaan naar de basis, zodat we de oefeningen goed en technisch correct leerden uitvoeren. Daarna werden de trainingen steeds zwaarder en uitdagender. Echt doelgericht en afgestemd op ons niveau. Wat we ook heel fijn vinden, is dat Saskia verder kijkt dan alleen de training. Ze kijkt mee naar onze voeding en leefstijl en geeft ons praktische en persoonlijke adviezen waar we echt iets aan hebben. En het is ook nog eens altijd gezellig! Na de training een lekkere proteïneshake en gezellig napraten over de training, maar soms ook gewoon over het leven. Voor ons is het daardoor echt veel meer dan alleen een training!

Saskia is de allerleukste personal trainster bij B-one Wat ik zo bijzonder vind aan Saskia, is dat het bij haar niet alleen om sporten gaat. Ze kijkt echt naar jou als persoon en biedt ook een stukje begeleiding en therapie wanneer je dat nodig hebt. Ze heeft een ontzettend fijne, warme en begripvolle manier van werken, waardoor je je gehoord en gesteund voelt. Elke sessie voelt eigenlijk als een combinatie van werken aan je lichaam én aan jezelf. 💪🏼🧠❤️
