STHENOSFITSthenosFit vs TrueCoach
TrueCoach is one of the most established program-delivery platforms for personal trainers, and plenty of good coaches run their business on it. SthenosFit (coaches usually shorten it to "Sthenos") is built for a different job — generating and adapting the programming itself. Here is what each platform is actually for.
TrueCoach delivers programs. SthenosFit helps you build them — and adapts them. SthenosFit's generator drafts every session against peer-reviewed strength and conditioning research with the citation visible per exercise, reads sleep, HRV and heart rate from your clients' wearables into a daily readiness score, and flags the clients who need you before they drift. If your bottleneck is writing and adjusting programming, that layer is the difference.

What makes SthenosFit different
Programs with receipts
A multi-stage AI pipeline drafts every session against peer-reviewed strength and conditioning research. The citation behind each exercise is visible to you and your client — and the generator learns your coaching style as you edit.
Biometrics that act
Most platforms show wearable data on a graph. SthenosFit folds sleep, HRV, heart rate and hormonal cycle into a daily readiness score that informs the next session automatically.
A roster that warns you
Pattern analysis surfaces falling adherence, poor recovery and injury risk before they become a cancelled subscription — with a daily briefing per client that you approve before it ships.

Choose SthenosFit if…
- Programming quality is your edge, and you want every prescription backed by visible research.
- You want your clients' wearable data to actually change their next session, not just sit on a chart.
- You want to know which client needs you today, before they drift.
