§ 01 — OmniFit Analytics
OmniFit Analytics
Coach with signals, not guesses.
A research-referenced analytics engine turns RIR proximity into hypertrophy stimulus, separates fatigue cost from Stimulus ROI, tracks acute-to-chronic load with EWMA and distributes synergist muscle impact using EMG-calibrated ratios.
6 minweekly reporting
Muscle distribution, ACWR, Stimulus ROI, e1RM and wellness — automatic analytics for every athlete.

§ 02 — Approach
Data only matters once it becomes a signal.
A coach's day disappears into replying to athlete messages, finding last week's sets in a spreadsheet, checking PRs in a notebook and estimating muscle distribution. The data exists, but it is scattered. Repeating the same loop for every athlete takes more time than writing the program.
OmniFit Analytics breaks that loop. It calculates weighted stimulus credit and fatigue-cost ROI from each set's RPE, tracks acute-to-chronic load with EWMA, converts EMG-based muscle impact across 114 exercises into regional stimulus and shows wellness beside training output. You design the program; the signal is ready when the decision is made.
§ 03 — Modules
Every measurement becomes a coaching signal.
01
ACWR — Acute:Chronic Workload Ratio
A workload ratio calculated with Gabbett's (2016) EWMA methodology. It compares 7-day acute load with the 28-day chronic average and shows a separate 14-day baseline period for new athletes.

calculated ratio
02
RPE · stimulus engine
Each set's RPE becomes RIR; rep position and a load proxy produce gradual stimulus credit. The ROI layer shows the fatigue cost of that stimulus.

§ 04 — Spotlight · Load management
Manage load with data, not feel.
The athlete enters RPE for each set; the system calculates weighted rep-equivalents, gross stimulus and fatigue-cost ROI. EWMA-smoothed 7-day acute load is divided by the 28-day chronic average, and you can examine all signals across the date range you choose.
- → Set-level RPE → automatic RIR, weighted stimulus and Stimulus ROI
- → EWMA-based acute/chronic ratio and raw components
- → 14-day baseline-period marker

§ 05 — Science · Hypertrophy Engine
Gradual stimulus, not a binary cutoff.
The old binary threshold cut a set off abruptly. The new engine weights each rep's stimulus contribution by RIR proximity, its position within the set and an Epley-based load proxy. The score is not a claim of measured hypertrophy; it is a research-informed stimulus estimate for coaching decisions.
RIR
Contribution rises smoothly as the set approaches failure.
Load proxy
Estimated maximum reps carry the load context.
Position
Early and late reps in the same set do not receive the same credit.
ROI
Gross stimulus, fatigue cost and readiness context stay separate.

§ 06 — Spotlight · Regional volume
Stop guessing muscle distribution.
Muscle-impact ratios for 114 exercises are calibrated with 25+ peer-reviewed EMG studies. Primary, secondary and stabilizer roles create a hierarchical distribution from 32 anatomical muscles to 13 regions. Every set becomes regional stimulus credit automatically.
See direct and indirect volume separately and spot imbalances in the radar chart.

§ 08 — Comparison
Four things a spreadsheet cannot do.
01
Acute/chronic workload ratio
Use EWMA to divide 7-day acute load by the 28-day chronic average and show a 14-day baseline period for new athletes. The ratio and components are live for every athlete; training interpretation remains with the user.
02
Exercise-based regional volume
You do not enter in a spreadsheet that a bench press contributes 30% to the sternal pec, 8% to the clavicular pec and 18% to triceps. EMG-based muscle ratios are defined for 114 exercises, so every set becomes regional volume automatically.
03
Readiness, stimulus and ROI relationship
Generate readiness from sleep, stress, fatigue and muscle soreness, then interpret gross stimulus and fatigue-cost ROI separately.
04
The athlete's mobile experience
The athlete completes a set, enters RPE, sees a PR celebration, gets an automatic rest timer and can log offline. It is a mobile product — a spreadsheet cannot do this.

§ 10 — FAQ
Questions coaches ask.
What if my athlete does not want to use the platform?+
You can enter the workout yourself even if the athlete does not join — sets, reps and weight included. Tonnage, ACWR and e1RM are still calculated when RPE and wellness are empty. Athlete participation deepens the analytics but is not required.
Do I own my data?+
Yes. All athlete and workout data belongs to you. You can export it or delete your account at any time.
How do I add exercises that are not in the library?+
Add your own exercises to the library and define muscle-impact percentages with primary, secondary and stabilizer roles. Define it once; regional volume updates automatically whenever it is added to a program.
Do I need to install an app on mobile?+
No. OmniFit Analytics runs as a PWA in the browser and can be added to the home screen. You do not need to wait for App Store or Play Store approval.
What is the monthly price?+
