What is the Best 4-Day Gym Workout Split for Muscle Growth?
The Short Answer: The "Upper/Lower" split is the most scientifically proven 4-day gym routine for beginners and intermediates. By training your upper body and lower body twice per week each, you perfectly balance muscle protein synthesis (which lasts 48 hours after lifting) with adequate recovery time. This drastically outperforms traditional "bro-splits" (like training chest only once a week).

Gym Rules for Success
Progressive Overload
You must do more than last time. Add 1.25kg weight, do 1 more rep, or improve form every session. If you aren't progressing, you aren't growing.
Consistency is King
A mediocre program done consistently beats the perfect program done sporadically. Don't skip Monday.
