Sound familiar?

You train hard. You're just not sure it's adding up.

Effort has never been your problem. A system that turns that effort into measurable, repeatable progress is.

✕

Random programs off the internet that ignore your actual strength, schedule, and history.

✕

No idea if you're progressing. Just a vague sense you're lifting "about the same" as last month.

✕

Spreadsheets and PDFs you open twice and then abandon by week three.

✕

Plateaus with no clear reason why, and no plan for what to change next.

There's a better way to train: a coach, a plan, and a system that keeps score for you.

How it works

Three steps from stuck to structured.

No long forms, no guesswork. A simple path designed to get you training with intent, fast.

01

Book a discovery call

A relaxed ~20-minute conversation about your goals, training history, and what's been getting in the way. We work out whether we're a fit, with no pressure either way.

Free · no obligation
02

Get your custom program

Your program is built as periodized phases (accumulation, intensification and beyond), with every load calculated from your real limiting lifts, not a generic template.

Built around your numbers
03

Train in the app

Open it, see today's session, log each set as you go. The app keeps score, tracks your trend phase to phase, and your coach adjusts the plan as you progress.

Always know what's next

The difference

This isn't a PDF. It's a living system.

  • See your whole week at a glance

    The Training Matrix lays out every session, and every prescription: sets, reps, tempo, rest, all calculated to your target intensity.

  • Loads from your real numbers

    The Limiting Lifts engine sets every working weight from your own maxes, so you're always lifting the right load, never guessing.

  • Progress you can actually see

    Log each set as you train. Watch your strength trend climb from phase to phase. Proof the work is paying off.

David Robertson · Online Strength Coach

Build on your strengths. Train what’s holding you back.

Coaching is provided directly by David Robertson, an Online Strength Coach who has coached clients since 2008.

Your program starts with your goals and current strength. We build on what you do well, then focus your training on the lifts and areas that need the most attention. Each phase has a clear purpose, and your coach adjusts the plan as you progress.

A stronger, more capable body doesn't stay in the gym. Clients carry that discipline, energy and confidence into the work and life they care about most. That's the whole point of building an infinite body.

Questions

Before you book, you're probably wondering…

What actually happens on the discovery call? +

A relaxed 20-minute conversation, with no slide deck and no hard sell. We talk through your goals, your training history and what's been getting in the way, and figure out together whether coaching is the right move for you right now.

Do I need to be advanced or already strong? +

No. The whole approach is built around your current numbers and starting point. Everything scales to you, whether you're rebuilding a base or chasing a specific lift.

What if I have an injury or medical condition? +

Strength coaching does not diagnose or treat injuries or medical conditions. If pain, an injury, or a medical condition affects your training, seek advice and clearance from an appropriately qualified healthcare professional. We can then decide whether coaching is appropriate while staying within that guidance and the scope of strength coaching.

Is this online, in person, or both? +

Programming and the app are fully remote, so you can train wherever you are.

What is the app, and does it cost extra? +

It's the system you'll train inside: your sessions, prescriptions and strength tracking in one place, on web, iOS and Android. Access comes as part of your coaching. There's no separate consumer signup.

How much time per week does it take? +

We design the plan around the time you realistically have, not an ideal you can't sustain.

What does coaching cost? +

Strength-only coaching is typically equivalent to US$400–$500 per month, depending on the coaching period. Period-specific bundle discounts are available. Book a free discovery call and we’ll talk through the options that fit your goals.
