Mirror, mirror on the wall — who's the fairest of them all? Private Personal Trainer in Dallas — 1-on-1 Glute & Lower-Body Training with Weekly Body Composition Scans

Wrong question. The mirror can't see muscle showing up, fat coming off, or the shape that's already starting to change.

What gets measured improves —
the BBZ Scan proves it weekly.

The Program

Most trainers adjust every six weeks. I adjust every Monday.

Your body gives me data every seven days. I read it, change the plan,
and text you what's different.

If this is you

  • You've tried everything and the scale won't move
  • You want stronger glutes, not smaller numbers
  • You're tired of guessing what's working
  • You want proof, not promises
  • You want to be coached, not cheered

What you leave with

  • A BBZ Scan, tape measurements, and progress photos
  • A plan rewritten every week based on your numbers
  • Nutrition in targets — no rules, no shame
  • Private sessions only — no floor traffic, no shared attention
  • If your current workouts haven't moved the needle in months — they will here

What you see in the work

  • A fresh plan every week
  • Numbers that moved (or didn't) — either way you'll know
  • A text from me with what to change
  • Honest feedback — what's working, what's not
  • Next week's focus in plain English

Most trainers give you a consultation. I give you your data. First, the BBZ Scan breaks down your muscle, your fat, and where it's sitting — in 60 seconds.

Then we train together for 45 minutes, one-on-one, using what the scan just showed me. You leave knowing more about your body than you ever have — and you've felt how I train, not just heard about it.

FAQ

Most Common Questions

Do you train one-on-one or groups?

One-on-one only. Groups are fine for cardio — they don't work when I'm trying to read your form and your scan in the same hour.

Is this only for women?

No. Most of my clients are women and gay men chasing a stronger lower body, a better waist-to-hip ratio, and a physique that doesn't need filters. If that's what you want, you're in the right place.

I've plateaued for months. Will this work?

Plateaus are almost always something the scale can't see. Your scan will surface it in week one — usually hydration, sleep, or muscle loss no one caught. We'll know what's really going on by week three.

Where do you train?

I come to you. Downtown Dallas, Uptown, Arts District, Design District, Trinity Groves, Deep Ellum, Victory Park, Oak Lawn. Your building's gym, a private studio, wherever works. Text me and we'll figure out logistics.

What does the scan feel like?

You stand on a platform, hold two handles, sixty seconds. No needles, no radiation, nothing weird. Results sync to an app we look at together.

How fast can I book?

Usually within the week. I only take a handful of new clients at a time — the weekly scan reviews stay personal that way. Text me and I'll tell you what's open.

About

I'm Zack.

You probably met me at Booty Bootcamp — the class packed every week with people training for how they want to look, not how much they can lift.

My private clients are done guessing. Done with programs written for guys chasing bench PRs. Done settling for “strong” when what they want is shape.

Bootcamp is the door. One-on-one is where your body finally answers.
