Is Vassiveness Exercise Specific?

At ON, we view Vassiveness as a state of appearing both massive and vascular. We have a whole line of products dedicated to supporting this goal. Now the American College of Sports Medicine offers a scientific study on the topic. Researchers wanted to know if increases in arterial size (aka: vascular remodeling) is regionally limited or more systemic. In other words, does Vassiveness occur only in the muscle being worked?

Twenty four previously untrained men and women were recruited for a 12-week unilateral strength training program focused on the biceps and triceps of nondominant arms. Scientists used magnetic resonance imaging to determine brachial artery diameter and muscle cross sectional area. The results showed that arterial diameter increased only in the trained nondominant arms.

The Bigger Picture: Because the physical changes were localized to the muscles being worked, those just beginning a resistance training program should consider whole body training during each gym session. Then, after gaining experience and muscle mass, you can graduate to split workouts where upper body muscles are worked one day, and lower body muscles the next. Another popular way to break training into split sessions is pushing and pulling movements.
