Why a 4-Day Split Routine Works

A 4-day split routine divides your weekly workouts into four sessions, with each day targeting specific muscle groups. This structure allows you to:

• Maximize focus per session: You’re not rushing through five or six exercises for every major body part. You can give each muscle group the time and intensity it deserves.

• Allow proper recovery: Muscles grow during rest, not during training. A 4-day split gives each group ample time to recover between sessions.

• Improve strength and hypertrophy: When organized well, split routines allow for progressive overload—one of the cornerstones of strength and muscle gain.
