Expert Insight: The 2-On, 1-Off Rhythm
The 4-Day split gained popularity because it matches the human work week perfectly. **CNS Recovery:** Training heavy for more than 2 days in a row drains the Central Nervous System. The 4-day split (Mon/Tue On, wed Off, Thu/Fri On) builds in a "Refresh" day right in the middle, allowing you to attack the second half of the week with full power.
