Best 4 Day Workout Split for Building Muscle

The sweet spot for most lifters. Upper/Lower or PHUL-style splits for optimal gains.

Four days a week is the golden zone—enough frequency for growth, enough rest for recovery. Popular splits like Upper/Lower and PHUL thrive here. RepLog makes tracking your 4-day split effortless.

Expert Insight: The Weekend Warrior's Dream

The 4-day split (Mon/Tue, Thu/Fri) is perfect because it gives you weekends off. **Social Recovery:** Recovery isn't just physiological; it's social. Having weekends free prevents burnout. RepLog's calendar view highlights this balance, showing you your "Green" training days and your "Grey" recovery days in perfect harmony.

Frequently Asked Questions

What if I miss a day?

Just shift the schedule. RepLog doesn't force days of the week; it tracks the sequence.

Is PHUL better than Upper/Lower?

They are similar, but PHUL undulates intensity (Power days vs Hypertrophy days), which RepLog supports natively.
