For lifters, runners, hybrid athletes and the gyms that coach them

Training that trains back.

Log the session you actually did, not the one on the plan. The Forge reads it, weighs it against what the block expected, and rewrites next week to match. One engine across powerlifting, hybrid racing, hypertrophy, marathon builds and more.

The adaptive spine

A PDF doesn't know you had a bad week

A programme you bought as a static plan is identical on your best week and your worst. The Forge is not. The AI is built into the programming itself, not a chatbot bolted onto a workout log.

You log

Every set you record is data. The weight, the reps, the RPE, and the sessions that never happened. That is the input the engine works from.

It reads

The engine compares what you did against what the block expected. A heavy week that beat you up looks different in the log from a heavy week you owned, and it can tell which one it was.

It rewrites

Next week changes before you get to it. Fatigue running high, volume comes down. Three sessions missed, the plan recalibrates instead of guilt-tripping you.

The catalogue

Every discipline, one engine

Powerlifting, bodybuilding, hybrid racing, functional fitness, marathon builds, strength and conditioning, GPP. The powerlifting blocks run on RPE and block periodisation, written by people who actually compete.

SBD Foundation

Squat, bench, deadlift. The base block everything else stands on.

Meet Prep & Peaking

RPE and block periodisation into a peak that lands on meet day.

Hybrid Racing Fitness

Engine and station work for hybrid racing, year round.

Hybrid Race Prep

A structured build that finishes on race day, not the week after.

Hypertrophy Block

Volume with a target. Sets that earn their place in the session.

Strength Block

Heavy work, planned progression, loads that come from your log.

Boxing Conditioning

Rounds and intervals with recovery that holds up late.

GPP Engine Builder

General capacity for whatever your sport asks next.

Competition Prep

A run-in built around a date on the calendar.

General Fitness

Consistent, adaptive training with no competition required.

The founder

Built by a world champion. Who is also an accountant.

The Forge was built by a WDFPF world powerlifting champion. The same person spends the working day building software for accountants, which sounds like a strange combination until you notice that both jobs reward the same habit. You write down what actually happened, not what the plan said should happen. You adjust to it. Then you turn up the next day and do it again.

That habit is what The Forge automates. Honest logging in, honest programming out.

Same log book discipline. Different bar.

For gyms and coaches

See the drift before the cancellation email

The admin level puts every member's training in one dashboard. Most members don't cancel loudly. They stop logging, then stop coming, then the email arrives. The Forge shows you the first step while there is still time to act on it.

Monitor

Every member's sessions, adherence and trends in one place. You see who is training, who is progressing, and who has gone quiet.

Message

In-app messaging, next to the training it is about. A short note from a coach at the right moment does more than any retention campaign.

Step in

Churn flags surface the members who are drifting, like nine days without a log, so someone can reach out before the direct debit gets cancelled.

What you get

A plan that holds up in a real training year

Programming with a memory

Next week is written from the sessions you logged, not from a week number in a template. What you lifted decides what you lift.

RPE that means something

RPE-driven loading and block periodisation across the strength work, written by people who compete under a barbell.

Every discipline, one account

Powerlifting, bodybuilding, hybrid racing, functional fitness, marathon builds, strength and conditioning, GPP. Switch programmes without switching apps.

Miss a week, keep the plan

Life happens. The Forge recalibrates around missed sessions instead of pretending they happened or nagging you about it.

A gym and coach level

Gyms and coaches see every member’s training in one dashboard, with flags on the people who are drifting.

Messaging inside the app

A coach note lands next to the session it is about. No chasing phone numbers, no separate group chat.

Questions

Asked before you ask

Which disciplines does it cover?

Powerlifting, bodybuilding, hybrid racing, functional fitness, marathon builds, strength and conditioning and GPP. The catalogue includes SBD Foundation, Meet Prep & Peaking, Hybrid Racing Fitness and Hybrid Race Prep, Hypertrophy Block, Strength Block, Boxing Conditioning, GPP Engine Builder, Competition Prep and General Fitness.

How does the adaptation actually work?

You log your sessions: sets, weights, reps, RPE, and the sessions you missed. The engine compares what happened against what the block expected and rewrites the week ahead. Fatigue running high, volume comes down. Sessions missed, the plan recalibrates rather than piling the backlog on top of you.

I run a gym or coach clients. How do we get set up?

The gym level lives in the same app. Set it up at theforge.capstonesoftware.co.uk, link your members, and their training appears in your dashboard with messaging and drift flags built in.

Does the price include VAT?

Yes. £12.99 a month or £99 a year, VAT included. The price on this page is the price on your statement.

Can I cancel anytime?

Yes. Monthly rolls month to month and you can cancel whenever you like. The annual plan is there if you want the cheaper year, not because you are locked in.

Twenty seconds of it

Watch next week rewrite itself

You log the session you actually did. The RPE runs hot, so the block adjusts. That is the whole difference between this and a PDF.
