Meet Sammy. Your recovery, training history, and goals — turned into a clear plan for today.
For iPhone and iPad.
Readiness is moderate; run the planned session at controlled intensity.
Only readiness changes here. In the app, Sammy weighs every signal.
Works with your day.
How it works
A simple daily loop, built around you.
Connect a wearable or check in. Your recent training and goal give the numbers context.
See what to do today, with a plain-language explanation of what mattered.
Train, adjust, or skip. Log how it went so tomorrow starts from what actually happened.
One example, explained.
Readiness comes from a connected wearable or your check-in. These values are illustrative, not your data.
Confidence reflects how complete today's inputs were: a readiness reading, a planned session, and enough training history.
From yesterday: RPE 8/10 — feeds today's load picture.
Your recovery reading this morning, 0–100, from a connected wearable or your check-in. It sets today's training band.
Recent training load against your longer-term average (ACWR). It describes change; it doesn't predict anything.
How similar your recent sessions have been. High monotony flags a deload.
What you reported in your check-in. High soreness eases the session.
Whether your check-in flagged an energy deficit for the day.
Sessions completed and skipped over the last 7 days. A long break eases the call back in.

The science
See what Sammy considered, why it made the call, and where the limits are.
Keep the session but cap intensity.
Readiness is 64 this morning, down 9 from yesterday, which sets a moderate training band. Yesterday's session landed hard (RPE 8/10) and feeds today's load picture; load is steady (ACWR 1.12) and didn't change the call.
Evidence we build from
Self-reported wellness can inform training decisions, but missing signals stay unknown and no single signal decides readiness.
Session RPE multiplied by duration is a practical way to describe internal training load when RPE is recorded.
Acute:chronic workload ratio can describe load change, but it is not a causal personal injury predictor.
Athlete sleep recommendations should acknowledge uncertainty and never turn short sleep into a diagnosis.
In Sammy, sleep feeds Readiness; it is not a separate signal.
Resistance training prescriptions should reflect the athlete’s goal, capacity, and training status.
Limits, stated plainly
Sammy is not clinical, diagnostic, or an injury-prediction system. Its readiness weights are hand-tuned coaching logic, not outcome-validated medical models. It is built to support general fitness decisions — not replace qualified care.
