Calculators
Free, no-signup tools that compute a result from your input.
Convert any sprint split — 10–20, 10–40, 10–60, or flying 10 — into an equivalent 40-yard dash time using a peer-reviewed sprint model.
Compute the Acute:Chronic Workload Ratio from 7-day acute and 28-day chronic load averages, with the 0.8–1.3 sweet-spot interpretation.
Guides & long-form articles
Coach-written explanations of the metrics and software decisions in this space.
How a composite 1–99 score combines speed, power, agility, jump, and strength using a peer-reviewed sprint model and NFL Combine calibration.
The science behind the sprint model that powers Tru40 — why simple multipliers fail and how the population-calibrated regression actually works.
The Acute:Chronic Workload Ratio formula, a 28-day worked example, the rolling-average vs EWMA debate, and an honest take on the research.
A coach's honest comparison of six platforms — Performance House, TrainHeroic, Volt, TeamBuildr, Metrifit, CoachMePlus — with a decision matrix and pricing snapshots.
What's actually included in Performance House Starter, what isn't, who it's for, and how it compares to the other tools' "free" options.
Head-to-head comparisons
Performance House vs each major alternative — features, pricing, honest verdict.
The enterprise AMS vs the self-serve modern AMS — pricing, sales cycle, AI insights, hardware integrations, who wins where.
The S&C programming app vs the full AMS — Program Builder depth, video review, pricing tiers, and where each tool wins.
The monitoring-focused tool vs the AMS that includes monitoring — wellness depth, programming, AI, and whether one tool can replace both.
The marketplace programming app vs the full AMS — flat-vs-per-athlete pricing, the AMS layer TrainHeroic doesn't ship, and where the marketplace genuinely wins.

About the library
Everything here is maintained as the product evolves. The calculators share their math with the in-app code, the protocols cite peer-reviewed research, and the comparison pages get refreshed when competitor pricing changes. Spot something stale? Email a correction and we'll fix it.
