The Behaviour Strength System
Because growth isn’t luck. It’s discipline.
Every product has muscles. Most never train them.
That’s where we come in.
We’d seen it too many times:
Features shipped, nobody touched them.
Funnels leaked, growth flatlined.
Teams hustled harder, nothing stuck.
The problem wasn’t the product.
It was weak behavioural fitness.
So we built a system, one that trains products like athletes.
Focus. Form. Frequency.
Week after week.
Any product. Any funnel. Any stage.
Any size, sector, or pressure.
The foundation
We use a combination of consumer psychology (how people buy, decide, and stay loyal), workplace psychology (how teams think and align), behavioural systems (habit-forming product environments), and decision dynamics (the levers that make people say yes or no).
Together they are the power behind your lifts.
The 4 pillars of strength
Mindsets → Muscles → Moves → Metrics
The framework every product runs through.
The Mindsets
Focus. Form. Frequency.
The three disciplines that build Behavioural Strength™.
We drill teams to fix one weak spot at a time, run clean reps, and move weekly.
That’s how you build products that don’t stall when growth gets heavy.
The Muscles
The four growth muscles every product must train to lift:
Activation: Shorten time-to-value.
Engagement: Build depth on what matters.
Retention: Stop the slow bleed, lock the gains.
Revenue: Fair upgrades, trial→paid, ARPU lift.
The Moves
A playbook of 10 behaviour backed exercises.
From sparking an early “Aha” to fixing last-mile friction, each move is designed to hit one muscle, one week at a time.
One move. One rep. One measurable lift.
The Metrics
The scoreboard doesn’t lie.
Signals inside 72 hours.
Deltas, not vanity totals.
15-40% lifts in 30 days when cycles stack.
Proof you can flex in a board deck and know you earned it.
The weekly cycle
How products train inside BehaviourGym:
Scan the Weak Spot → find the leak that costs most
Pick the Muscle → activation, engagement, retention, or revenue
Run One Move → tested play from our kit
Read the Signal → proof in 72h, no stories
Decide Friday → scale, iterate, or kill
Repeat Next Week → compounding gains, no stalls
Just reps. Just results.

Strength Scan
Your first step isn’t a sprint. It’s a scan.
Find the weak spots before you train.
The sprint advantage
30 days. One weak spot. Measurable lift.
We don’t move into your Slack.
We hit like a personal trainer: fix the leak, drill the form, leave you with the playbook.
Why it works
Because behaviour follows patterns.
Because Focus beats scatter.
Because compounding strength comes from one clean rep at a time.
We turn behavioural science into sweat:
Habit formation. Friction design. Advocacy loops.
The science that makes growth predictable.
FAQs
What if there’s no lift?
We kill or iterate. No sunk-cost theatre. The log shows why. The next move starts Monday.
What if we can’t ship weekly?
Then we plan biweekly heavy days. Fewer reps, same discipline.
Will this work for enterprise?
Yes, if we can isolate a muscle and ship reps inside a controlled surface (pilot, line-of-business, or a single flow). See how we work with portfolios.
How is this different to a workshop?
Workshops talk about reps. We do reps. You leave with lift and a library, not post-its.
Is this ethical?
Yes. Form over hacks. Yes. Form over hacks. Fair value exchange. No dark patterns. Gains that last.
