This split typically follows a , allowing you to hit every muscle group twice a week—a frequency research suggests is optimal for both muscle hypertrophy and strength development. Core Principles
Each muscle is trained twice every seven days, maximizing muscle protein synthesis. Upper Lower Strength and Size Program
The most effective upper/lower programs, such as (Power Hypertrophy Upper Lower) or Jeff Nippard’s versions, are built on these pillars: This split typically follows a , allowing you
