I'd been wanting to get back in shape for a while, but between work and travel I could never stick with anything. A friend recommended Castillo Private and it's honestly been the best decision. The personal trainer comes to your home here in Miami, so there are no more excuses — no commute, no packed gym. But what really makes them different is that it's not just "train and goodbye" like every other trainer I'd tried. It's a complete system: they handle your training and your nutrition, everything's tracked in their app, and there's a weekly check-in so you actually stay consistent. A few months in and I've dropped weight, I'm noticeably stronger and I have so much more energy day to day. Everything is tailored to me, and the team is professional and discreet. If you're looking for a private, in-home personal trainer in Miami, look no further.

Few years aho I had an accident that made me feel scary about lift any weight, at my 30 years old I was thinking about: what kind of life I’m gonna have if I’m not able to lift anything? Thanks to Alex, Adrian and all the team to made me lose my scary ik the gym and teach me the right technique, now I feel more active than before my accident. If you are a person with special conditions and you are looking for a profesionals that can help you on the right way Deffinetly you have to call Alex and his team. Highly recomended

Alex is the real deal - European, high energy and combines real expertise with an elevated, professional approach. His sessions are focused, efficient, and genuinely results-driven. He corrected my form on lifts after years of doing them wrong and the difference was immediate. A trainer worth the investment!

I can’t recommend Alex and Adrian enough. As a 52-year-old who has had back surgery, I was honestly nervous about getting back into a fitness routine (after a 4 years hiatus). I needed trainers who understood my limitations while still helping me get stronger and healthier. I couldn’t risk a back injury. What really sets Alex and Adrian apart is that they work as a true team. They don’t just show up for the workouts—they’re invested in your overall success. They keep me accountable with my meal plan, regularly check in on my nutrition, and recommend adjustments when needed. Every month they take measurements and track my progress, which has been incredibly motivating because I can actually see the results instead of just guessing. They pay close attention to proper form and technique, which has been especially important for me. I always feel challenged, but never unsafe. Beyond their knowledge and professionalism, they’re simply great people who genuinely care about their clients. They celebrate your successes, encourage you when you’re struggling, and create an environment where you actually look forward to showing up. If you’re looking for trainers who truly care about your health, hold you accountable, and guide you every step of the way—not just in the gym, but with nutrition and long-term progress—I wholeheartedly recommend Alex and Adrian. Hiring them has been one of the best investments I’ve made in my health, and I feel stronger and healthier than I have in years.

Questions

An app gives you a plan. Here, a private team runs the plan for you — prescribing, reviewing and adjusting every week.

If you are in Miami, yes — a monthly in-person evaluation is part of the system where geography allows.

The structure adapts to your calendar and location; oversight continues wherever you are.
