The Arm and Delt Specialization program is designed around increasing volume and frequency in opposing waves.
In weeks 2, 4, and 6 the number of sets per body part in a given week increases.
In weeks 3 and 5, the weekly volume scales back slightly to accommodate for recovery as training frequency continues to go up.
Either volume or frequency will increase every week.
The slightly lower total volume starting in week 1 is a necessary jumping off point to allow the body to begin in an optimal state to ensure weekly progression.
If your goal is to add extra growth to your arms and delts, this is the program for you.
