You are as fit as you are competent in each of these 10 skills, and a regimen develops fitness to the extent that it improves each of the 10 skills.

Importantly, improvements in endurance, stamina, strength, and flexibility come about through training. Training refers to activity that improves performance through a measurable organic change in the body. By contrast, improvements in coordination, agility, balance, and accuracy come about through practice. Practice refers to activity that improves performance through changes in the nervous system. Power and speed are adaptations of both training and practice.

If your goal is optimum physical competence, then all 10 general physical skills must be considered and developed.
