“Most PT software is glorified data storage with a subscription attached. BuildStability is different.”
Vinay Koka · Founder, Synergy Training & Health

“It’s built for PTs first and foremost, not just an app that works for your clients. I’m an actual PT with face-to-face and online clients who switched, and couldn’t be more convinced this is the holy grail.”
Ad Coutts · Ad Coutts Personal Trainer
A program in seconds. Not Sundays.
Describe your client. AI writes a periodised plan from their actual history, not a template. You review, tweak, assign.
- Reads real history
Injury notes, RPE trends, last session’s actual load. Not a generic template, not a population average.
- Edits in-line
No PDF exports. No emailing the plan. No “did you get my program?” The client opens the app, the plan is there.
- Same builder, every sport
HYROX periodisation, healthy-ageing progressions, hybrid lifting, running base. One builder, every sport you coach.


Not “senior fitness”. Actual age-appropriate programming.
Training stimulus and recovery windows change every decade. The AI plan builder picks intensities, progressions, and deload cadences appropriate for each client’s age bracket. Not a watered-down 25-year-old’s program.
Strength and load capacity. Bone density loading. Cardio base.
Power-based training. Balance progressions. Joint-friendly hypertrophy.
Fall prevention. Sit-to-stand power. Gait speed. Reactive balance.
Chair exercises. Assisted standing. Grip strength. Aqua modalities.
Rikli & Jones Senior Fitness Test, built in.
Six validated assessments with age-and-sex normative benchmarks. Score each client on the Active Living Indicator (0–100) and track improvement across six-month windows.
One number. 0 to 100. Your client’s functional age in a glance.
A weighted composite of the six assessments. Building Foundation → Developing → Progressing → Active → Thriving.
- Six-assessment weighting
Sit-to-Stand 25%, Timed Up and Go 20%, grip 15%, balance 15%, gait 15%, flexibility 10%. Aligned with the Rikli & Jones published protocol.
- Visible to client and trainer
Score renders on the client dashboard, the trainer view, and every shareable report. The number a 70-year-old can actually read.
- Trend the return on coaching
Re-measure quarterly. The trend line plots the gain. Proof your coaching is moving the needle, not just keeping someone busy.
Share progress with your client’s GP. The right way.
One-click report: assessments, program history, RPE trends. The client signs consent before anything leaves your system.
- Consent before every share
Recorded per share, audit trail per client. Aligned with the Australian Privacy Principles. The PT-client privacy posture done properly.
- Scope-of-practice disclaimer
Every report carries: "Fitness progress data within scope of practice as a PT. Not a clinical assessment." Protects your professional posture.
- No other PT platform ships this
A consent-recorded, scope-disclaimed GP workflow built into the platform. Not bolt-on. Not a generic PDF. Built for the PT-GP referral loop.
The AI reads the chart before it writes the plan.
Flag the condition on the client’s intake form and the AI plan builder applies the right contra-indications automatically. You still review and sign off. The automation is a guard rail, not a substitute.
No loaded spinal flexion. Weight-bearing standing work prioritised. Bone-loading progressions.
ROM limits respected. Squat depth capped at 90°. Progression gated on surgeon clearance.
Double warm-up. Lower-impact cardio. Loading reduced on flare days.
Cardio every session. Blood-glucose monitoring prompts before and after.
Scope-of-practice guard rails applied in the AI plan builder. Trainer review required before any plan is assigned to a client.
Vegemite. Snags. Weet-Bix. In your food database.
Your clients shop at Coles, not USDA. Repley sets protein and calorie targets from the training block. Clients log a Bunnings snag in two taps. No second app. No subscription on top.
- Five ways to log
Barcode, label photo, meal photo, chat with Repley, voice. Every method included on every paid tier.
- Targets, not menus
Macros adjust for training day vs rest day. Clients log what they ate, not what an app prescribed.
- Protein that protects lean mass
Targets tuned to hold muscle after sixty. The metric that matters most for healthy ageing, tracked without a second app.
- Competitors lean on USDA
Their food data is American. Their sync layer is MyFitnessPal. Your client doesn’t shop at USDA.

Or build by hand. Faster than you remember.
Some clients you write yourself. Pick split, goal, equipment. The day grid arrives pre-shaped. No blank canvas. No copy-pasting from last week’s Google Doc.
- Skeleton in three picks
Split, goal, equipment. The grid arrives pre-shaped with movement-pattern slots. Push / Pull / Legs in one click.
- Prescription shorthand
3×8 @RPE8 90s parses straight into Sets, Reps, RPE, Rest. One keystroke instead of four dropdowns.
- Auto-saves every two seconds
Section headers (Strength, Accessories, Finisher) appear as you build. Never lose work to a closed tab.

Onboarding that runs itself, so you can take on more.
The part of growing you keep putting off now sorts itself. Send one link and the waiver, screening and payment are handled, every client the same way.
- One link, no app
They sign and screen from a phone or browser. Nothing to download, no password, the same for every client.
- Nothing slips through
Flag a condition on the AU and NZ screening and they wait in a review queue. You clear, modify or hold, on the record.
- Money arrives on its own
Near trial end they get a card link, add a card with no login, and billing starts. You never send the awkward text.


Your clients already use AI to train. You should too.

Matt Crofts · CPA · 25 Years Software
Apps like Fitbod and JEFIT sell your clients AI workouts for $10/month. Every PT tool I tried just stored data and charged for it. So I built one that fights back. AI that works for trainers. Not against them.
