The Best 4-Day Workout Routine: Upper/Lower Done Right

Four training days is one of the most productive setups for natural lifters. It gives enough time to train each muscle twice weekly, enough room for accessories, and enough rest to recover.

The weekly layout

A classic schedule is Monday upper, Tuesday lower, Thursday upper, Friday lower. Each muscle is trained twice per week. Keep at least one rest day between the second lower day and the next week if leg sessions are hard.

Upper days

Upper A: bench press, row, overhead press, pulldown, lateral raise, triceps, biceps.

Upper B: incline press, pull-up or pulldown, dumbbell press, chest-supported row, rear delts, arms.

Balance pushing and pulling so shoulders stay healthy.

Lower days

Lower A: squat, Romanian deadlift, leg press, leg curl, calves, core.

Lower B: deadlift or hip thrust, front squat or split squat, leg extension, hamstring curl, calves, core.

Use heavy compounds first and isolation work after.

Volume and progression

Most muscles land around 10 to 18 hard sets weekly with this split. Progress compounds slowly, add reps on accessories, and deload if performance drops for multiple weeks.

Key takeaways
  • Four days works beautifully as upper/lower.
  • Each muscle is trained twice weekly.
  • Balance pressing with rowing and pulldowns.
  • Use compounds first, accessories second.

Frequently asked questions

Is upper/lower better than push pull legs?

For 4 days, usually yes. Push pull legs fits best at 5 to 6 days, while upper/lower gives a simple twice-weekly muscle frequency in four sessions.

Can beginners use a 4-day routine?

Yes, if recovery and schedule are good. Many beginners do great on upper/lower, especially after a few months of full-body training.

How many exercises per workout?

Usually 5 to 8 exercises. More than that often becomes low-quality volume unless sessions are very well managed.
