Full Body vs Split Workouts: Which One Should You Choose?

What the research says about frequency and splits

A 2016 meta-analysis by Schoenfeld and colleagues found that training a muscle twice a week produced more growth than once a week. However, a 2019 follow-up that focused on studies where weekly volume was equal found no meaningful difference between training a muscle one, two or three or more times a week. More frequent sessions mainly help because they make it easier to fit in more quality sets.

Direct comparisons point the same way. A 2024 meta-analysis by Ramos-Campo and colleagues found no significant difference in strength or muscle growth between split and full-body routines when volume was matched. The 2026 American College of Sports Medicine position stand recommends training all major muscle groups at least twice a week and stresses that the best program is the one you'll stick with.

The main workout splits explained

Every split is just a different way of spreading the same work across the week. Here's what each option looks like and who it tends to suit.

• Full body: every session trains legs, push and pull muscles. Usually 2–3 days a week, each muscle 2–3 times.
• Upper/lower: alternates upper-body and lower-body days. Usually 4 days, each muscle twice.
• Push/pull/legs (PPL): chest-shoulders-triceps, back-biceps, then legs. Run twice through in 6 days, each muscle twice.
• Body-part or ABC split: each day focuses on one or two muscle groups (for example A: chest/triceps, B: back/biceps, C: legs/shoulders). Done once a week, each muscle gets one session; repeated as ABCABC, it gets two.
• Hybrids: for example upper/lower plus push/pull/legs over 5 days.

How to choose by the days you have

Start from your real schedule, not your ideal one. A plan that assumes six sessions but gets four each week leaves some muscles untrained, while a three-day full-body plan completed every week keeps everything moving forward.

• 2 days a week: full body both days (for example Monday and Thursday).
• 3 days a week: full body on non-consecutive days (Monday, Wednesday, Friday).
• 4 days a week: upper/lower, twice each.
• 5 days a week: upper, lower, push, pull, legs — or upper/lower plus one full-body day.
• 6 days a week: push/pull/legs twice, best for experienced lifters who recover well.

How to choose by experience and lifestyle

Beginners usually do well with full-body training 2–3 times a week. Practising the main lifts often helps you learn technique, and modest volume per session is enough to progress. Intermediate lifters often prefer upper/lower or PPL because more weekly sets fit without very long sessions.

Also consider session length, other sports and personal preference. Full-body workouts are longer but fewer; splits make each session shorter and more focused but need more days. If you often miss sessions, choose a plan where every muscle is trained at least twice, so one missed day doesn't mean a muscle goes untrained for two weeks.

Sample weekly schedules

These templates use roughly 10–15 hard sets per major muscle per week. Rest days can move, but avoid hard sessions for the same muscle on back-to-back days when you can.

Example full-body session: squat 3×6–8, bench press 3×6–10, row 3×8–12, Romanian deadlift 2×8–10, lateral raise 2×12–15, curls 2×10–15. Alternate with a second session that uses different variations, such as leg press, overhead press and pulldowns.

• Full body (3 days): Mon A, Wed B, Fri A; the following week Mon B, Wed A, Fri B.
• Upper/lower (4 days): Mon upper, Tue lower, Thu upper, Fri lower.
• Hybrid (5 days): Mon upper, Tue lower, Wed rest, Thu push, Fri pull, Sat legs.
• Push/pull/legs (6 days): push, pull, legs, push, pull, legs, then one rest day.
• ABC twice (6 days): A, B, C, A, B, C, rest — so each muscle is trained twice.

Common mistakes when picking a split

Most problems come from a mismatch between the plan and your life, not from the split itself. Watch out for these:

• Picking a 6-day plan when you can reliably train only 3 days.
• Running a once-a-week body-part split with low volume, so each muscle gets only a few hard sets per week.
• Cramming too many sets into full-body sessions until quality drops at the end.
• Letting legs or back fall behind because they are scheduled on the day you usually skip.
• Switching programs every few weeks instead of progressing on one for at least 8–12 weeks.
