The short version
- A split is how you divide your training across the week.
- Training each muscle about twice a week tends to beat once a week for muscle growth.
- Pick the split that fits the days you can actually train.
Choose by days per week
| Days | Split | Each muscle per week |
|---|---|---|
| 2–3 | Full body | 2–3× |
| 4 | Upper / lower | 2× |
| 3 or 6 | Push / pull / legs | 1× (3 days) or 2× (6 days) |
| 5 | Upper/lower + full body | 2× |
What matters more than the split
- Weekly sets: about 10 or more hard sets per muscle per week is linked to more growth, built up gradually.
- Effort: finish sets 1–3 reps before failure (RPE 7–9).
- Progressive overload: add reps or weight over time (how).
- Consistency: the best split is the one you do for months.

Common mistakes and fixes
- Program-hopping every two weeks. Fix: Run one split for 8–12 weeks.
- Copying a pro’s 6-day split on 3 days. Fix: Match the split to the days you really have.
- All volume, no recovery. Fix: Add sets gradually and take a lighter week every 6–8 weeks.

Questions people ask
Is push/pull/legs good for beginners?
Yes on 6 days; on 3 days it trains each muscle once a week, so full body is often better for 3-day beginners.
Can I train the same muscle two days in a row?
Usually give a muscle 48 hours between hard sessions.
