BIG (Compound) vs SHREDDED (Isolation) | Marvin Achi

This fitness video features Marvin Achi explaining the difference between compound and isolation exercises, and how to weight a programme toward one or the other depending on whether the goal is size, definition, or a combination of the two. It is aimed at viewers deciding how to structure a training week rather than at anybody looking for a single session to copy.

Framelink Media edited it as an explainer rather than a workout. The two ideas are kept visibly separate so a viewer can tell which half applies to them, compound lifts are shown as whole movements and isolation work is framed on the single joint doing the work.

The video was prepared for publication with both sides of the comparison labelled on screen, so a viewer scrubbing through can find the half that applies to their own goal without watching the whole explanation.

The finished video is one people watch sitting down while planning a training week, and suits anybody deciding how to structure their programme.
