Low volume or beginner routines are often full body workout training splits.

Advantages to full body workout routines:

High volume routines cannot be full body routine. They advocate many sets per muscle group, making it impossible for a full body workout. Full body routines are low volume focusing around efficient compound excercises. Depending on the workout routine, you can hit each muscle group 1-3 times a week.

Full Body Workout Routine:

There is various types of full body workout programs. Most are 2 or 3 workout day splits. The amount of sets per muscle group varies between workout program. Some extreme hardgainer routines only recommend one set per muscle a week, while HST for example, recommends multiple sets per muscle group a week.
