Each of the rowers represents a system which may be a potential limiting factor to performance.

1.  Cardiac (heart)
2.  Respiratory (lungs)
3.  Neuromuscular (nerve and muscle)
4.  Metabolic (chemical reactions at a cellular level)

How can you design a training program without being able to determine which of these rowers are  your limitation?

Only through testing of each of these systems can you know how to train effectively and efficiently. 

This is the purpose of Paragon Sports.
