WELCOME TO EMPIRICAL TRAINING & NUTRITION
Bodybuilding, Powerlifting, Military Fitness & Lifestyle Coaching
My name is Paul Serafini and I am an online fitness coach located in Melbourne, Florida. I provide online fitness coaching that includes personalized training programs and/or nutrition plans. I help clients achieve their goals through 1-on-1 online coaching, whether they’re training for bodybuilding, general muscle building (hypertrophy), powerlifting, military fitness tests, strength training, fat loss, or improving their overall health and performance.
Every coaching program is completely individualized. Your training plan and nutrition strategy are designed specifically around your experience level, lifestyle, schedule, training history, and long-term goals. There are no generic templates or one-size-fits-all programs.
How My Online Coaching Works
When you sign up for coaching with me, you’ll receive:
- A fully customized workout program tailored to your goals.
- A personalized nutrition plan based on your body composition, performance goals, and lifestyle.
- Weekly online check-ins to review your progress, training performance, recovery, and nutrition adherence.
- Ongoing adjustments to your training and nutrition based on your progress, feedback, and performance data.
- Direct coaching, accountability, education, and support throughout your fitness journey.
My data-driven approach ensures your program continues to evolve as your body adapts, helping you make consistent progress while minimizing plateaus.
Evidence-Based Coaching That Gets Results
I’m not just a guy who got into exercise, my fitness journey started in the army where I began reading research to help me achieve my own goals the best I can. This led me to actively involved in producing research and I have even become a published author with several publications. Most of my research background came from Kennesaw State University where I received a Master’s in Applied Exercise Physiology. I combine sports science, strength and conditioning principles, and real-world coaching experience to create effective, sustainable programs. Every recommendation is grounded in current research while remaining practical and realistic for your lifestyle.
