Trinity Training Facility · West Covina, CA
Strength is the foundation everything else stacks on. Trinity's strength & conditioning trainers build athletes, professionals, and lifelong residents who want to move heavy, recover hard, and keep doing it for decades.
01
ASSESSMENT FIRST
Movement screen, training history, current lifts. Your trainer builds the program around your body — not a template they hand to every client.
02
PROGRESSIVE OVERLOAD THAT HOLDS UP
Programmed cycles with deloads built in. You'll see the numbers move week over week without burning out.
03
CONDITIONING THAT DOESN'T KILL YOUR LIFTS
Energy-system work paired with strength training, not against it. Capacity grows. Recovery improves. Strength stays.
04
TRAINING ON THE FLOOR
Hands-on cues, video review, real-time form correction. Every session has a trainer who's watching.
Who Marissa’s clients tend to be
- Lifters chasing real PRs — not gym numbers
- Athletes whose sport demands repeatable power
- Professionals returning to the iron after years away
- Anyone tired of training without a program
