## What is Overload?

Overload sets your training targets for you, and shows you the research behind every rule it follows.

TARGETS FOR EVERY SET
Each session, Overload tells you what to lift: the weight, the reps and how close to failure to go. Targets come from what you actually logged last time, not from a fixed rep range. Change the weight and it predicts the reps.

VOLUME THAT ADAPTS
After each muscle group, answer a few quick questions: how the workload felt and whether anything hurt. Next time, it asks if you're still sore. A set is added only when a session felt easy and you hit every target. Sets come off when you're not recovering.

TRAINING BLOCKS WITH A DELOAD
Effort rises week by week until the last hard week, then a deload week lets fatigue clear before the next block starts a little heavier.

EVERY RULE HAS A SOURCE
A short tour explains each rule exactly as the app applies it, with links to the studies on PubMed. Where a rule has no direct study behind it, the app says so.

SEE YOUR PROGRESS
Charts of weight, reps and volume for every exercise, week by week.
