Meet Nemezio LopezPerez
Founder & NASM Elite Trainer — OmniFit Performance · 4S Ranch, San Diego
Training Built Like the Rest of Your Life
Most of my clients are busy professionals over 30 who've outgrown how they used to train. Joints complain more. Schedules own them. They run every other part of their life with structure and data — but can't seem to apply the same rigor to their body. Generic gyms, group classes, and six-week challenges haven't closed the gap.
OmniFit Performance is built for that specific problem. Every program begins with a 45-minute consultation and a 9-point movement screening, then follows the same four-stage framework: Assess → Correct → Build → Sustain. We assess what's actually breaking down, correct the patterns driving it, build strength on a foundation that holds, and sustain the result after coaching ends. That framework is why most clients lose 20–30 pounds over 4–6 months without the joint pain, plateaus, or burnout that usually come with aggressive fat loss.
My own history shaped this approach. Years of athletic injuries, a long rehab arc, and extensive study of corrective exercise taught me what most gyms never learn: strength training should make your body more durable, not less. Every OmniFit client is held to that standard.

Where Performance Meets Metabolic Health
OmniFit Performance operates from Teqneeq — a members-only functional health and performance lab in 4S Ranch that integrates training with an on-site physical therapy clinic. This environment is the physical embodiment of our methodology: structured training that bridges the gap between rehabilitation and peak performance.
Through a certified collaboration with Eden — a network of metabolic health professionals — OmniFit extends that bridge into metabolic health, supporting clients navigating GLP-1 medications, peptide protocols, and medication-assisted fat loss. Three Eden certifications back this scope of work.
GLP-1 Fitness Certification
Training methodology for clients on GLP-1 medications — protocols to preserve lean mass, manage energy fluctuations, and adapt training volume to the metabolic shifts that occur during medication-assisted fat loss.
Peptide Fundamentals Certification
Working knowledge of how peptide-based therapies interact with training load, recovery demands, and body composition goals — so exercise programming complements clinician-guided protocols rather than working against them.
GLP-1 Nutrition Certification
Nutrition coaching tailored to clients using GLP-1 therapy — protein prioritization, micronutrient density, and sustainable habit architecture designed to protect long-term metabolic health and lean tissue.
OmniFit Performance is not a medical provider and does not prescribe, administer, or recommend medications, peptides, or clinical protocols. All medication-related decisions remain with the client's licensed healthcare provider. These certifications inform training and nutrition coaching so it safely complements clinician-guided care.
The OmniFit Mindset
Every OmniFit program is built on four principles that separate structured coaching from random workouts.
Assessment Before Assumptions
Every program starts with a 45-minute consultation and 9-point movement screening. We never guess — we measure, then build.
Corrective-First Training
Joint health comes before heavy lifting. The 3/10 pain ceiling rule governs every session, protecting your body while building capacity.
Data-Driven Progress
Seven metrics tracked monthly — body composition, strength, posture, mobility, adherence, nutrition, and well-being. Formal 30-day reports drive every adjustment.
Independence as the Goal
The benchmark for success isn't whether you keep paying us. It's whether you keep your results long after your program ends.
Competitor, Athlete, Coach
As an active purple belt in Brazilian Jiu-Jitsu with multiple tournament wins and a background in track, soccer, and rugby, I bring the same discipline and competitive drive to coaching that I demand from myself on the mat.
