Compound vs. isolation exercises

Compound exercises involve several joints and muscles (like squats and bench press); isolation exercises work one joint and one main muscle (like curls and leg extensions).

Also known as: Multi-joint vs. single-joint

Compounds let you use more load and train many muscles at once, which makes them efficient as the base of a program. Isolation work adds targeted volume to a specific muscle and corrects weak points a compound alone does not cover.

It is not one against the other: most good plans combine both, with compounds first (while you are fresh) and isolation after. SelfShapeAI builds that order for you, choosing and sequencing exercises according to goal, equipment and available time.
