Physique Skool Exercise Library
735 exact setups across 22 muscle groups. The tier scores the biomechanics model. The evidence grade tells you how much direct support sits behind that judgment.

Tier lists by muscle
Every card opens a standard S-to-C tier board. The Priority Pyramid remains an optional teaching view inside each muscle page.

How the library works
We define the target and the exact setup first. Then every option faces the same eight mechanics checks: target demand, resistance path, usable muscle length, stability, progression, joint fit, fatigue, and practicality. We also change the weighting to see whether the placement survives. Scores use absolute thresholds, not a forced curve, so a muscle can have several strong options without pushing one down to fill a lower tier.
Physique Skool Law: Score the setup, not the exercise name.
The exercise identity, target, and exact setup are defined before any comparison begins.
The same biomechanical model tests target demand, resistance profile, stability, progression, and fatigue for every exact setup.
Alternative weightings and context reversals determine whether a placement is ranked, special-use, or held.
Exercise selection rubric
Every rank starts with a biomechanical model of one muscle and one exact setup. The model traces target demand, resistance profile, stability, progression, and fatigue before assigning a tier.
Physique Skool LawScore the setup, not the exercise name.
Can the exact setup reliably bias the intended muscle instead of a neighboring limiter?
How directly the setup trains the muscle being ranked.
Can the target produce meaningful tension through a useful range of motion?
The quality of load the target receives across the rep.
Does the setup provide enough support for effort to reach the target muscle?
Whether balance and bracing help the lift or steal from it.
Can load, reps, range, and execution be progressed and measured consistently?
How cleanly the exercise supports repeatable overload.
Can the lifter train hard through tolerable positions without avoidable joint irritation?
The usable overlap between hard training and joint comfort.
How much non-target fatigue is paid for the local stimulus the exercise creates?
Local return relative to systemic, axial, grip, and setup fatigue.
Is the equipment, setup, loading, spotting, and transition cost realistic?
How easy the movement is to perform well in a real program.
Does the exercise suit the lifter's structure, skill, history, and preferences?
The personal factors that can override a useful default.
Method
Theory produces the default rank. Evidence confidence and known context reversals stay visible beside it.
Step 01
Compare one precise variation, target, and evidence set before judging the movement.
Step 02
Trace the target action, line of force, moment demands, muscle length, and resistance profile through the rep.
Step 03
Check whether equipment geometry, stability, another limiter, joint fit, or program role reverses the theoretical default.
Separate lens: Program contribution
Coverage, redundancy, time efficiency, and equipment access determine whole-program ROI. They do not change a muscle-specific score.
Separate label: Evidence confidence
Confidence reports how directly the available research supports the judgment. It never becomes bonus points for the exercise itself.
