STHENOSFITSthenosFit vs Superset
Superset is a serious S&C training platform: spreadsheet-style AI periodization, a deep exercise-video library, and unified records for multi-coach teams. SthenosFit is narrower and deeper on the science — research-cited AI sessions, daily readiness from wearables, cycle-aware and injury-aware programming — at one flat, published price.
Both tools generate AI training programs, but they aim at different coaches. Superset is built for teams and S&C-minded coaches who live in a spreadsheet workflow: its AI turns an athlete description into a full periodized block (Superset Sheets), it ships an exercise-video library of 1,000+ demonstrations you can attach to programs, and it standardizes client records across multiple coaches. The trade-offs are commercial — pricing is opaque (a sales call produces a base fee plus per-client fees), automated payments carry a surcharge on top of standard Stripe fees, and the client app stays under the Superset brand.
SthenosFit trades breadth for a specialist system. Each session is drafted in multiple stages against peer-reviewed research with the citation visible per exercise; a daily readiness score from sleep, HRV and resting heart rate auto-adapts the session; programming is cycle-aware and flags injury-risk patterns on the roster; and you approve an AI client briefing before it ships. The price is one flat plan for up to 20 clients, published, with a 14-day trial. SthenosFit takes in-platform payments via Stripe Connect (a platform fee applies). It deliberately omits things Superset has — exercise demo videos, nutrition tracking, group challenges — so be honest about which side of that line your practice sits on.

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.
Which one should you choose?
Choose Superset if…
- You want a built-in exercise video library you can attach to client programs — Superset ships 1,000+ demonstration videos, SthenosFit has none.
- You run a multi-coach team and need standardized, shared client records across staff in a spreadsheet-style S&C workflow.
- You want nutrition visibility inside the same tool — Superset's Cronometer integration lets you set macro targets and monitor client food logs (it's tracking, not meal-plan creation).
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.
Why we build it this way
Superset gives S&C teams a spreadsheet with AI bolted on. We give a coach research-cited programming they can defend exercise by exercise — at a flat, transparent price that never takes a cut of their payments.
That focus is a deliberate trade. We don't ship a nutrition database, a stock video library, habit checklists or a white-label reskin — and we are not going to. Every hour of engineering goes into the two things that decide whether a client stays: programming drafted from current research, and training that bends to how they actually recover. If you want one app that does a little of everything, we are honestly the wrong choice. If you want the sharpest programming you can put your name on, there is nothing closer.
Looking for a Superset alternative?
If your coaching leans on exercise demo videos, nutrition tracking, or a shared workflow across a team of coaches, Superset is the stronger fit and worth the sales call. SthenosFit is the better choice when the program itself is the product: research-cited AI sessions, daily readiness from sleep/HRV/resting heart rate that auto-adapts the workout, cycle-aware and injury-aware programming, and coach-approved daily briefings — sold as one flat published plan for up to 20 clients rather than a quote-based base-plus-per-client model. Both offer a 14-day free trial.
Common questions
Does Superset cost more than SthenosFit?
Superset doesn't publish a public price — you book a sales call for a custom quote, typically a base subscription plus per-client fees, plus a surcharge on top of standard Stripe fees for automated payments. SthenosFit is one flat published plan for up to 20 clients, so you know the subscription cost before you commit; in-platform payments run through Stripe Connect and a platform fee applies. Both include a 14-day free trial.
What can Superset do that SthenosFit can't?
Superset includes a 1,000+ exercise video library you can attach to programs, nutrition tracking through its Cronometer integration, and unified client records designed for multi-coach teams. SthenosFit has none of those — no exercise videos, no nutrition tracking, and it's built around a solo or small-roster coach rather than large teams.
What does SthenosFit do that Superset doesn't?
SthenosFit drafts each session in multiple stages against peer-reviewed research with the citation shown per exercise, calculates a daily readiness score from sleep, HRV and resting heart rate that auto-adapts the workout, programs around the hormonal cycle, flags injury-risk patterns on your roster, and generates a daily client briefing you approve before it ships. Superset's AI focuses on periodization and progression rather than this biometric and research depth.
