The Best Workout Split for Your Schedule

There is no best split; there's only the best split for the days you'll actually train. Muscle growth tracks weekly volume and effort; the split is just how you package it. So pick by schedule, not by influencer.

By days per week

2-3 days → Full body. Every session hits everything: squat or hinge, push, pull, and a little arm or core work. Three full-body days deliver 6+ weekly sets per muscle from the big lifts alone; the beginner plan is this exact structure.

4 days → Upper / Lower. Two upper days, two lower days. Each muscle trained twice weekly with real recovery between. The most forgiving intermediate split there is:

• Upper A: bench, row, overhead press, curls
• Lower A: squat, RDL, leg curl, calves
• Upper B / Lower B: swap the emphasis (incline + pulldown; deadlift + press variations)

5-6 days → Push Pull Legs. Movement-pattern days, run once-and-a-half to twice weekly. Highest volume ceiling, but it needs the most schedule discipline. Full breakdown in the PPL guide.

The rule that outranks the split

Frequency beats novelty: each muscle wants ~2 quality exposures per week, with total weekly volume in the 10-20 hard-set range. Any split that delivers that, and that you show up for, works. The classic "bro split" (one muscle per day) fails mostly because each muscle waits seven days between stimuli.

Switching splits

Change when your schedule changes or progress genuinely flatlines for 6+ weeks, not every time a new program catches your eye. And when you do switch, keep logging: volume per muscle should survive the move, even as the packaging changes.
