60 seconds to a periodised HYROX plan. Per client.
Tell the AI your client’s goal race, their weak station, their current 1-mile pace, and their training days per week. It writes the periodised block: base, build, peak, taper. You review, tweak, assign.
- All 8 stations with official race-weight prescriptions baked in.
- Weak-station targeting: extra volume and drills where it matters.
- Compromised running sessions built from station + run combos.

Show them the change. Or watch them drift.
Every client gets a 90-day arc. Day 0 takes 30 seconds. Day 7, 14, 30, 60, and 90 fill themselves in from the workout logger and the calendar. Day 90 is a page they share.
- Day 0 in 30 seconds
Goal and starting weight by default. Optional toggles for 1RMs, body measurements, starting photo. Skip what doesn’t matter.
- Six milestones, mostly auto
Day 0, 7, 14, 30, 60, 90. Strength PRs and adherence land on the right milestone automatically. No manual journaling.
- Day 90 they share
The arc ends with a celebration page the client posts. Referrals follow without you asking.
For the clients the journey did not reach.
A real-time signal across bookings, sessions, and billing that flags drift roughly 30 days early. Save the client before they ghost.
- 30-day early-warning
Reads bookings, logged sessions, billing patterns, and adherence. Flags drift before the client decides to leave.
- Transparent scoring
Every flag shows the why. You see exactly which signals tipped a client into the at-risk bucket. No black box.
- Opt-out per client
Some clients don’t want a score. Switch it off for them. Their data stays yours, never trained on, never sold.

Money shows up. In your account. With a receipt.
Stripe Connect means clients pay you directly. We never touch the money. GST invoices in your business name. Exports your accountant won’t complain about.

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.
