Yes, upper lower is excellent for growth because it hits each muscle twice a week with manageable session volume.
Upper lower is one of the best splits for hypertrophy because it trains each muscle group roughly twice a week, which is the sweet spot for frequency. Running it four days a week lets you accumulate 10 to 20 hard sets per muscle without any single session becoming exhausting junk volume. It also balances compounds and isolation well and fits a normal schedule, making it easy to progress and recover.
A four-day upper lower rotation hits every muscle about twice a week, which research supports as ideal for spreading volume with quality reps. Each muscle gets a fresh, hard session and 48-plus hours to recover before the next.
Because the week is split across four sessions, no single workout has to cram 20 sets for a muscle. That keeps every set crisp and lets you hit 10 to 20 weekly sets per muscle across two days rather than grinding them all fatigued in one.
Upper lower fits a common four-day schedule and lets you anchor each session with a compound you can progressively overload. Add a fifth or sixth day if you want more volume, or run it as three days on a rolling basis if time is tight.
