BUILD THE PROGRAM YOU'LL ACTUALLY FOLLOW
Start from a coach-built Cornerstone template or a blank canvas — set your weeks and days, then program every set with percentages, RPE, and RIR. No spreadsheets.
PUSH DAY
START FROM A PROVEN TEMPLATE
Pick from a library of coach-built Cornerstone programs — Cornerstone Method, Mighty Fortress, Iron Sharpens Iron, The Master Builder, and more — beginner to advanced, home gym to commercial, sorted to your experience level.
Preview the whole thing, then load it and make it yours.
Cornerstone Method
The introduction to the Cornerstone ethos — full-body strength and size, three days a week.
Iron Sharpens Iron
A classic push/pull/legs split with free weights and machines to stack serious size.
SET YOUR WEEKS AND DAYS IN SECONDS
Choose anywhere from 1 to 16 weeks and 1 to 7 training days a week. Add a week and Cornerstone duplicates your layout, so you're never rebuilding from scratch.
PROGRAM THE EFFORT, NOT JUST THE WEIGHT
Set a target RPE or reps-in-reserve for any exercise — set by set — so each lift is as hard as it should be, not just a number on the bar.
It's how the research says to train: for hypertrophy, keep most sets within about three reps of failure; for strength, stay one to four reps from it — roughly RPE 6 to 9.
Switch an exercise between percentages, RPE, and RIR whenever the block calls for it.
