Watch First

See how DMF coaching works

Before you book anything, hear it straight from Derek — who this is for, how the coaching works, and what happens on your Discovery Call.

Watch: the DMF training overview

Who This Is For

You take care of everyone else. Who's holding you accountable?

You're a busy dad or professional. Work is demanding, the family needs you, and somewhere along the way you let yourself go. You don't need another generic program — you need a plan built for your life and someone in your corner making sure it happens.

  • ✕The gut keeps growing and your energy is gone by mid-afternoon.
  • ✕You start strong every Monday and fall off by Thursday.
  • ✕You know what to do — you just don't do it consistently.
  • ✕Your kids deserve a dad who's strong, present, and leading — not exhausted and checked out.
Who you are in Christ comes before what you do in the gym.

Most fitness programs start with your body and never touch the man. DMF starts with identity. When a man knows who he is, discipline stops being a fight — it becomes who he is. Training, nutrition, and habits follow from that foundation, and that's why the change lasts.

This isn't a quick fix or a 30-day shred. It's coaching for men who want to be strong for their families for decades — in body, in faith, and in how they lead at home.

Identity first · Then intensity

Proof

Real people. Real change that lasts.

Not influencers. Not 22-year-olds with no responsibilities. Husbands, wives, dads, and professionals with full lives — getting strong and staying that way.

7 months

Ron & Cathy

Started training twice a week. Seven months later, they're lifting four days a week with their nutrition consistent alongside the workouts. Strength, energy, and a healthier life — built together as a couple.

“Consistency became their lifestyle.”

50+ lbs down

Cliff

Cliff is 50+ lbs down and a stronger man — and it didn't stop with him. The way he leads his family changed with it. When dad gets healthy, the whole house feels it.

40 lbs · 9 months

Karolann

Karolann lost 40 lbs in 9 months without living in the gym. Short, focused training and a nutrition plan that fit her real life — proof you don't need hours a day to change your health.

Clients have been set free from addiction — because this was never only about the weight.

What Clients Say

“I love how my workouts are short and intense to make it work with my busy schedule.”
Ethan Swirtz — Coaching Client

Actual client experiences. Individual results vary. These are real clients and real results shared with permission. Individual results vary — your outcome depends on your starting point, consistency, and effort. Coaching is not a guarantee of any specific result.

The Brotherhood

Iron Sharpens Iron

No man grows alone. Iron Sharpens Iron is the men's faith & fitness group Derek founded in Florida — men who met Monday through Friday at 7 AM to pray, train, and fellowship before the day began.

That brotherhood is the heartbeat behind everything DMF teaches: men get sharper in the company of other men who refuse to let them stay where they are. It's the same accountability Derek brings to every coaching client — you were never meant to carry this by yourself.

“As iron sharpens iron, so one man sharpens another.”Proverbs 27:17

Speaking

Bring Derek to your church, event, or company

Derek speaks at churches, men's events, conferences, and companies — practical, faith-forward teaching that moves men and teams from knowing to doing.

  • Fitness with God: Identity Before Intensity

    The flagship talk — why lasting health starts with who you are in Christ, not another diet.

  • Daily Non-Negotiables

    The small daily disciplines that quietly decide a man's health, faith, and family life.

  • Strong for Your Family

    For men's groups and churches: becoming the strong, present leader your family needs.

  • The Healthy Team Advantage

    For companies: what a healthier team is actually worth — energy, focus, and culture.

Questions

Before you book

How much time does this take each week?
Less than you think. Training is built around your schedule, and busy-day sessions run 20–30 minutes. Most clients train 3–5 days a week in short, focused sessions — Ethan, one of our clients, puts it best: the workouts are “short and intense to make it work with my busy schedule.”
Do I need a gym membership or equipment?
No. Your program is built for what you have — a full gym, a garage setup, or just dumbbells at home. Training happens at home or in the gym, and your plan is adjusted to your equipment from day one.
I'm really out of shape. Is this for me?
Yes — that's exactly who this is for. You don't get in shape to start coaching; coaching is how you get in shape. Your program starts at your current level and progresses as you do. Most of our clients started out of shape, busy, and frustrated with themselves.
What if I have injuries or physical limitations?
Your program is custom-built around your limitations — bad knees, a cranky shoulder, an old injury. On your Discovery Call we'll talk through what you're working with, and your training is designed to build strength safely around it.
How does online coaching actually work?
Your workouts live in the Trainerize app, built personally for you. You train on your schedule, log your work, and check in weekly. Derek reviews your progress, adjusts your program, and coaches you on calls — you get a personal coach and real accountability without having to be in the same room, or even the same state.
What does it cost?
We'll discuss the coaching option, commitment, and pricing on your free Discovery Call. Every man's situation is different, and the call is where we make sure the fit — and the investment — makes sense before anything else.
What happens on the Discovery Call?
It's a free, relaxed 1-on-1 conversation with Derek. You'll talk through your goals, your schedule, and what's been holding you back. You'll leave with a clear next step either way — and if the Annual Transformation Program is the right fit, we'll walk through exactly what that looks like. No pressure, no hard sell.

Stop putting yourself on hold.

Your family doesn't need a perfect man. They need a strong, healthy, present one — and that starts with one free call.

Step 1

Choose a time

Pick a slot that works for you on the calendar — it takes less than a minute.

Step 2

Talk through your goals

Tell Derek where you are, where you want to be, and what's been in the way.

Step 3

Get a clear next step

Leave knowing exactly what to do next — whether we work together or not.
