- Body Recomposition
- Lifestyle & Longevity
I'm an ACE-certified personal trainer with three years of hands-on coaching, specializing in muscle building, weight loss, body recomposition, and lifestyle training. My approach blends scientifically backed techniques with real-world application so results actually stick — personalized programs built around your goals, fitness level, and life outside the gym. Consistency and enjoyment are the method; long-term health is the point.

Trinity Training Facility · West Covina, CA
Bodybuilding is patience translated to muscle. Trinity's hypertrophy trainers program volume, recovery, and nutrition in lockstep — so the work you put in actually shows up in the mirror.
01
VOLUME PROGRAMMED WITH INTENT
Every set has a target — failure, RPE 8, mechanical tension, metabolic stress. No junk volume.
02
PROGRESSIVE FAILURE PROTOCOLS
Drop sets, rest-pause, eccentric overload — the techniques bodybuilders have used for decades, programmed correctly so they actually drive growth.
03
NUTRITION TRAINING THAT PAIRS
Calories, protein, peri-workout fueling. Several Trinity trainers hold PN1 — or pair you with a nutrition specialist on the team.
04
PHOTO + MEASUREMENT TRACKING
Weekly check-ins. We look at the work, not just the scale. If it's not changing, the program adjusts.
Who Arias’s clients tend to be
- Lifters who want visible change, not just better numbers
- First-time competitors preparing for stage
- Clients chasing body recomp — leaner + stronger simultaneously
- Lifestyle clients who want a build that lasts

GET YOUR NUMBER
