About
Hello fitness family! My name is Nathaniel Rondez, and I’m a certified personal trainer based in Elk Grove, CA. I’ve been training clients since early 2019, but fitness has been part of my life since childhood through football and track.
I work with adults and young athletes to build strength, improve conditioning, and develop sport-specific skills, especially for football and track. My own journey recovering from a knee injury and the impact of my physical therapist inspired me to help others transform their lives through movement.
I offer in-person training and a full-featured online personal training app that makes remote coaching feel almost like we’re together in the gym.
If you’re ready to get stronger, move better, and train with purpose, I’d love to help you get there.

What stands out most about Nathaniel is how much he truly listens. He regularly checks in to see how my body is feeling and proactively adjusts my workouts based on my energy levels, soreness, and overall well-being. I never feel like I’m following a one-size-fits-all program. It’s clear that he’s genuinely invested—not just in how I look, but in how I feel and how my body functions. His attention, adaptability, and commitment have made a huge difference in my fitness journey, and I would highly recommend him to anyone looking for a trainer who truly cares about their clients.

I’ve been working out with him for couple of months now and have seen a lot of improvement in my strength because of his workout program. He makes sure I give my 100% for every workout and the program is designed for my goals. It’s great to workout with him and looking forward to continuing to do so.

I cannot recommend Nathaniel highly enough as a personal trainer for young athletes. As the parent of a 12-year-old boy who competes at a high level in travel ice hockey, finding the right trainer was critical. Nathaniel has been an absolute game-changer for our family.
From the very first session, Nathaniel stood out because of his deep understanding of youth athletic development. He truly gets the unique demands of athletics including ice hockey—explosive speed, agility, core strength, balance, and injury prevention—while keeping everything age-appropriate for a growing 12-year-old. His programs are smart, progressive, and never push too hard in ways that could risk overuse injuries, which was a big concern for us.
In just a short time working with Nathaniel, my son has shown noticeable, measurable improvements:
Faster skating speed and quicker first-step acceleration
Significantly better on-ice endurance and recovery between shifts
Stronger core and improved balance, which has translated directly to better puck control and stability during checks.
What I appreciate most about Nathaniel’s approach. He doesn’t just train the body—he teaches proper movement mechanics, emphasizes recovery and mobility. My son actually looks forward to his sessions, which says everything about how engaging and motivating Nathaniel is with kids this age.
Nathaniel is professional, patient, encouraging, and genuinely invested in each athlete’s success. He communicates clearly with parents and tailors every workout to the individual player’s goals and current season schedule.
If you have a youth athlete (especially in hockey or other high-intensity sports) and want real, sustainable results with someone who prioritizes long-term development over quick fixes, Nathaniel is the trainer you’re looking for. We’re incredibly grateful to have found him and plan to continue working with him for years to come.

Nathaniel is incredibly knowledgeable about the physical, mental and nutritional aspects of working out. He is dedicated, punctual, straightforward and methodical about his workout plans. I started training with him 3 months post knee surgery and less than a year later I am stronger, better balanced and overall more confident and able to enjoyallmy outdooractivities. He will help you achieve your goals whatever they may be. Absolutely 12 out of 10 recommend!

I was searching for a trainer on Google and came across Nathaniel. I've always struggled in the gym to make noticeable progress, but he helped make a complete 180 for me. It's quite uncommon to see the discipline he has and uses to help you reach your goals.
And whatever they might be, if it's athleticism or pure strength training, he will get you where you want to be.
Within a year I was able to put on over 30 lb of muscle and my strength grew considerably.
He is particularly great at what he does and is always reliable. Definitely recommend!!
