Full body vs split routine
Split routines (chest day, leg day) and full-body sessions both have loyal followings. When weekly volume is the same, a meta-analysis of 14 trials found no meaningful difference in strength or muscle growth, so the choice comes down to schedule and preference.

The options, compared
| Option | Evidence | Best for | The honest note |
|---|---|---|---|
| Full body (2–3 sessions a week) | Moderate evidence | Busy schedules, beginners, practising lifts often | Same growth and strength as a split when volume is equal; each muscle gets 2–3 sessions a week and a missed day costs less. |
| Upper/lower (4 sessions a week) | Moderate evidence | Training 4 days with each muscle twice a week | A middle ground with shorter sessions than full body; no trial shows it beats the others when volume is matched. |
| Body-part split (5–6 sessions a week) | Moderate evidence | People who enjoy long, focused sessions on one or two muscles | Works as well as full body when weekly volume is equal; one small trial in trained men saw slightly more thigh growth, but the pooled data show no difference. |
Our verdict
Pick the layout that lets you do your weekly sets with good effort and fits your week: full body for 2–3 days, upper/lower for 4, a split for 5–6 if you enjoy it. Train each muscle at least twice a week when you can, and keep total volume the same.
