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.
