Training With Zay

STRENGTH & CONDITIONING
AT TRINITY.

All Strength & Conditioning trainers

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 Zay’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

How It Works

NO MEMBERSHIP.
NO CONTRACT.

Trinity is a private training facility, not a gym you join. You book Zay; Zay books the floor.

01

FREE INTRO

Use the form below or call 626-430-7695. Zay reaches out within 24 hours.

02

WALK THE FLOOR

Goals, history, schedule, a movement screen, and a tour of the rooms your program will use.

03

GET YOUR NUMBER

Zay sets their own per-session and package rate and quotes it directly. You pay for sessions, nothing else.

04

TRAIN 24/7

Every session is an appointment. The building is open around the clock, so 5am and 11pm both work.
