<｜begin▁of▁sentence｜>### Instruction:
As a fitness trainer, imagine you're designing a new fitness program aimed at enhancing overall health and wellness for a group of five individuals. To ensure the effectiveness of your program, you want to assess the "central" role each exercise plays in improving overall fitness. In this scenario, think of each exercise as representing a vertex in a complete network of exercises, where each exercise is connected to every other exercise.

To accomplish this, you're interested in using the "Betweenness Centrality" concept from network analysis. This concept identifies exercises that act as important intermediaries in facilitating overall fitness improvement. By calculating the betweenness centrality of each exercise, you'll gain insights into which exercises play crucial roles in connecting different aspects of fitness within your program.

You'll utilize a specialized tool called "igraph" designed specifically for network analysis in fitness programs. With igraph, you'll be able to calculate the betweenness centrality of each exercise vertex within your complete network of exercises, helping you tailor your fitness program to maximize its impact on participants' health and wellness.
### Response:
import igraph as ig

# Assuming we have already created a graph named 'g'
# Example usage to calculate betweenness of vertices
g = ig.Graph.Full(5)
vertex_betweenness = g.betweenness()
print('Vertex betweenness:', vertex_betweenness)
