Does a split routine build more muscle than full-body training?
When weekly training volume is comparable, a recent meta-analysis found similar average strength and muscle-growth outcomes. The labels mostly describe how work is distributed. Session length, available days, exercise quality and what happens after a missed session can be more useful reasons to choose between them.
What the two labels describe
A full-body session includes work for several major regions in one visit. A split routine divides work across visits, for example upper and lower body or different movement groups. Neither label tells us the total weekly sets, effort or exercise selection. Two full-body sessions can contain less work than four split sessions, or the same amount distributed differently. A comparison is meaningful only after those quantities are visible. A split is not automatically advanced, and full-body training is not limited to beginners. Both are scheduling structures that can hold demanding or modest programmes.
