Two of the most common ways to structure a training week are Push Pull Legs (PPL) and Full Body, and despite endless online debate about which is "better," the honest answer is that each fits a different situation well. The right choice depends more on your schedule and recovery than on which is theoretically optimal.
What each split actually looks like
Push Pull Legs divides training into three session types: Push (chest, shoulders, triceps), Pull (back, biceps), and Legs (quads, hamstrings, glutes, calves), typically run 5-6 days a week, hitting each muscle group roughly twice weekly on a 6-day rotation.
Full Body trains all major muscle groups in every session, typically 3 days a week (e.g. Monday/Wednesday/Friday) with a rest day between each, hitting every muscle group three times weekly.
Full Body is usually better if...
- You can only train 2-4 days a week. PPL's structure assumes 5-6 sessions to work as designed, running it on 3 days a week means missing entire muscle groups regularly, which defeats its purpose.
- You're a beginner. More frequent practice of each core lift (squat, bench, deadlift, row, overhead press) accelerates skill acquisition for people still learning proper technique.
- Your schedule is unpredictable. Missing one Full Body session just means slightly less volume that week, missing one PPL session means an entire muscle group gets skipped until the next rotation.
Push Pull Legs is usually better if...
- You can commit to 5-6 sessions a week consistently. This is non-negotiable for PPL to actually deliver on its design, an inconsistent 5-6 day PPL routine performs worse than a consistent 3-day Full Body routine.
- You're at an intermediate or advanced level and want more total weekly volume per muscle group than 3 Full Body sessions can practically provide without every session running very long.
- You enjoy more exercise variety per session, PPL sessions typically include more total exercises per muscle group per session than a Full Body session has room for.
What the research actually says about frequency
Training a muscle group roughly twice a week reliably outperforms training it once a week for both strength and hypertrophy, once total volume is accounted for, a finding the American College of Sports Medicine reflects in its own strength-training frequency guidance. Beyond twice weekly, the additional benefit becomes smaller and more dependent on the individual, this is exactly why both a well-run 3-day Full Body split (each muscle ~3x/week) and a well-run 6-day PPL split (each muscle ~2x/week) both work well; they land in a similar effective frequency range from different structures.
A hybrid option worth considering
For people who can manage 4 days a week, more than Full Body strictly needs, less than PPL's full 6-day design, an Upper/Lower split (alternating upper-body and lower-body focused sessions) is often a better fit than forcing either extreme. It hits each muscle group roughly twice weekly like PPL, but only requires 4 sessions instead of 6.
The honest bottom line
Neither split is objectively superior, the split you'll actually complete consistently, at a frequency that matches your real schedule, will outperform a "better" split you only manage inconsistently. Be honest about how many days you can genuinely commit to before picking a program, not how many days you'd ideally like to train in a perfect week.
