We show our work.
Every chart and number in Powerhaus is backed by real science — and we publish exactly how each one is calculated, why it’s there, and where the evidence is strong (or, honestly, where it isn’t). No black boxes.
Estimated 1RM
The heaviest single you could lift — estimated from any hard set, so you never have to test a true max.
Read the science →In every tierPersonal Records
Three records per lift — your best single, five, and ten — tracked automatically from the sets you were already doing.
Read the science →In every tierMuscle Heat Map
A body map that shades each muscle by how much work it’s absorbed — so you can see at a glance what you’re hammering and what you’re neglecting.
Read the science →In every tierBodyweight as Load
A pull-up moves your bodyweight. We count that as real work — using an honest, clearly-labeled estimate of how much of you each move actually lifts.
Read the science →In every tierBest Weight & Best Volume
Two more ways to read the same lift — the heaviest load you moved and the total work you did — sitting right next to Est. 1RM.
Read the science →In every tierPlate Calculator
Tell it a target weight and it shows you exactly which plates go on each side — drawn out so you can match the bar plate for plate.
Read the science →In every tierBody Measurements
Track your weight and tape measurements over time — the honest, operator-proof way to watch your body change.

A read on which muscles are fresh and which you’ve hit recently — a training-frequency compass, told honestly as a clock, not a verdict.
Read the science →Training Intelligence · GoldDeload Detection
Spots the weeks where your training volume dropped hard — a useful mirror on your history, held up against a science that’s honestly still arguing with itself.
Read the science →Training Intelligence · GoldTraining Load (ACWR)
Compares your recent training load to your longer-term baseline — a well-known sports-science idea we ship with its warning label fully intact.
