Anterior / Posterior Program
"What does Anterior/Posterior mean?"
The typical bro-split or bodybuilder split is fine for the gym-goers who want to chase a pump and train every muscle a total of once per week. But studies show that training frequency is the highest contributing factor for muscle response. Meaning it matters less about how hard you train a muscle in a day and more how often you train that muscle throughout the week.
Anterior/Posterior refers to your body's Coronal Plane. Basically we are cutting your body in half. Not hamburger style, but hot dog style. Anterior refers to the front half of your body (chest, shoulders, abs, and Quads) and Posterior refers to the back half of the body (upper back, lats, lower back, glutes, hamstrings)
If you apply this 2 day split across 4 days per week, your muscular training frequency will double compared to a typical bro-split.
