Exercise Physiologists with College-Level Training
At Train with Dave, every trainer brings a college degree in exercise physiology to the table. This means your fitness program is rooted in science. Our trainers have an in-depth understanding of how muscles grow, how metabolism works, and how the body adapts to stress. This knowledge allows us to create programs that effectively tackle issues like chronic pain, metabolic hurdles, and specific body composition goals.
We take pride in our rigorous hiring standards. Our team includes former Fitness Managers and trainers who have published work in medical journals. To stay sharp, they participate in weekly training sessions to stay on top of the latest research [2].
Combined Exercise and Nutrition Expertise
At Train with Dave, we know that exercise and nutrition are two sides of the same coin. That’s why all our trainers must pass written exams on nutrition before they start working with clients [2]. This dual expertise means your trainer can help you fine-tune your macronutrient intake and meal timing to complement your workouts.
Take Susan’s story as an example. In August 2015, she lost 85 lbs through a program that combined personalized nutrition guidance with exercise routines tailored to accommodate a severe knee injury. Despite eventually needing a full knee replacement, Susan achieved her goals thanks to this balanced approach [1].
This integration of exercise and nutrition ensures every aspect of your fitness journey is covered, including safe and effective workout execution.
Proper Form and Injury Prevention
Our trainers’ education in biomechanics and corrective exercise equips them to spot and address movement issues before they lead to injuries. This is especially important for clients managing chronic pain or recovering from past injuries.
For instance, in April 2016, Richard came to Train with Dave to address chronic low back and hip pain caused by powerlifting. Through a corrective exercise program, he regained the ability to walk and bend without discomfort. Reflecting on his experience, Richard shared:
His corrective exercise knowledge has helped immensely. It was affecting my quality of life and I'm so grateful that I can now walk and bend over without any pain.
This level of expertise not only helps protect your joints and muscles but also ensures every workout is as effective as possible. Whether you’re recovering from an injury or simply want to train safely for years to come, our exercise physiologists build programs grounded in science to help you reach your goals.
Personalized Fitness and Nutrition Plans
At Train with Dave, every program is crafted to align with your personal data, goals, and lifestyle. As owner David Cozzens puts it:
Each Personal Training program is not only customized towards your goals, but is created to fit your lifestyle.
This individualized method has already helped over 1,000 clients achieve visible results across our Orange County locations [1].
Plans Built on Individual Data
It all starts with a free 45-minute consultation, where we dive deep into your current fitness level, movement patterns, and medical history [1][6]. During this session, we collect detailed information through body composition scans, posture analysis, and slow-motion gait evaluations. Beyond physical assessments, we also discuss lifestyle factors like sleep, stress, and daily routines to ensure your plan is practical and easy to follow.
Using this data, your trainer calculates your metabolic rate and identifies the ideal macronutrient ratios tailored to your needs. This approach ensures your program is grounded in facts, not guesses. As your body evolves, these ratios are adjusted to continue supporting recovery and energy demands [7]. This meticulous data collection allows for highly targeted programs designed to address your specific challenges.
Programs for Specific Goals and Challenges
Whether your focus is managing chronic pain, recovering from an injury, or achieving a specific body composition, your program is built to meet your unique needs. For example, in July 2016, Steven achieved a 13% body fat level and gained 18 pounds of muscle in just four months through a science-backed program. More recently, from April 2025 to September 2025, Uriel Perez worked with instructor Braeden to lose 33 pounds with a weight-loss plan tailored specifically for him [3].
Our trainers consider everything, from injuries like torn tendons and knee replacements to metabolic issues and food sensitivities. This level of detail ensures you're not following a one-size-fits-all plan - you're following a strategy designed exclusively for your body and your goals. This personalized approach allows for ongoing adjustments to keep your progress on track and aligned with your evolving needs.
Data-Driven Progress Tracking
Train with Dave uses data analytics technology to ensure clients see measurable results from their investment [1]. By tracking specific metrics, the program demonstrates its effectiveness in a tangible way. As the team explains:
Every weapon in our armory, from our top-notch trainers to our data analytics technology, is meant to produce the best outcomes in the shortest amount of time [1].
Proprietary App for Progress Monitoring
The program’s custom app is designed to track a wide range of metrics, giving a clear picture of your progress. It logs body composition scans to monitor body fat percentage and muscle mass, tracks daily caloric intake with macronutrient breakdowns, and even records factors outside the gym like sleep quality and stress levels. Additionally, it captures movement patterns, cardiovascular performance, and daily step counts [2].
In our own app, we track every metric for trainers and clients. It institutionalizes responsibility. It leverages data to refine your program [2].
This detailed tracking system ensures that every aspect of your fitness journey is accounted for, providing the foundation for precise adjustments when needed.
Evidence-Based Program Adjustments
The app’s data allows trainers to make timely adjustments to your program. For instance, if muscle gain is on track but fat loss is slower than expected, macronutrient ratios can be recalibrated. If poor sleep quality signals recovery issues, workout intensity is reduced. By using real-time information - such as body composition and sleep patterns - trainers fine-tune your program to keep progress steady [2].
The app also holds trainers accountable, pushing them to deliver measurable results based on the data they collect [3]. This approach ensures every decision is grounded in evidence, leading to better outcomes for clients.

Train with Dave offers three conveniently located facilities throughout Orange County. The main hub is at 303 E Katella Ave, Orange, CA, with additional locations at 16510 Aston St, Irvine, CA, and a facility in Laguna Hills to serve residents in Southern Orange County [4][6].
"Our strategically located facilities ensure a life-changing fitness journey is always within reach." – David Cozzens, Owner, Train with Dave [4]
These locations are designed to provide expert, personalized training no matter where you are in the area. This setup aligns with the company’s commitment to delivering science-based, results-driven fitness solutions across Orange County [6].
Private Training Environment
Each facility is tailored to create an ideal environment for personal training. Unlike crowded commercial gyms, these private spaces are distraction-free and equipped with specialized tools to enhance your fitness journey [1]. The design supports a scientific approach to body transformation, focusing on proper form, movement analysis, and hands-on guidance from college-educated trainers [4]. This ensures every session is effective and personalized to your needs.
"The gym has a nice area & clean atmosphere, Trainers are professional!" [3]
The professional atmosphere across all three locations allows trainers to dedicate their full attention to your progress, ensuring a focused and supportive experience.
Flexible Scheduling Options
To accommodate busy lifestyles, Train with Dave offers an online booking system that shows real-time availability, making it easy to plan sessions around work or family commitments [6]. The Irvine facility, in particular, caters to professionals and families, emphasizing flexibility to meet their unique needs [4].
"In the bustling city of Irvine, our facility caters to professionals and families looking for a balanced approach to fitness, combining cutting-edge training techniques with flexible scheduling." – David Cozzens, Owner, Train with Dave [4]
With sessions starting at $60, the program is designed to deliver maximum results in minimal time [1][3]. For times when in-person attendance isn’t possible, trainers provide custom workouts to ensure your progress stays on track, no matter your schedule [3].

Real Client Success Stories
Eric joined Train with Dave in October 2022. As a dedicated runner, his goal was to lose fat and build muscle. Trainer Gio created a plan tailored to Eric’s running background, helping him lose 15 lbs of fat and gain 5 lbs of muscle in just 6 weeks [5].
Daisy Torres started her journey in late April 2025. By July 2025, she had shed 20 lbs in 3 months through a personalized training program [3]. Similarly, Kelsey, who faced weight gain during the COVID-19 lockdown, achieved a 25 lb weight loss in 5 months with a program designed to address her specific challenges [1].
While weight loss is a common goal, more clients are focusing on functional fitness - like moving pain-free and improving metabolic health - rather than just aesthetic changes [8]. These stories highlight the commitment to creating lasting, meaningful results.
Creating Habits for Long-Term Success
Train with Dave’s programs go beyond short-term wins by emphasizing sustainable habits. Clients are educated on the "why" behind their workouts and nutrition plans, empowering them to make lasting lifestyle changes [1].
The approach includes behavioral strategies that build repeatable habits and foster the mental shifts needed for permanent results. Trainers also address areas outside the gym, such as improving sleep, managing stress, and increasing daily non-exercise activity. By focusing on these elements, the programs support overall wellness and help turn achievements into lifelong habits [1]. This comprehensive strategy ensures that every client’s progress is both meaningful and enduring.
