5. Energy producing system within the muscle that requires oxygen
6. Energy producing system within the muscle that is without oxygen
7. Training load expressed as weight, speed, or heart rate
10. The passageway, muscles, and lungs that allow muscles to be breathed in and carbon dioxide to be breathed out
11. The network of blood vessels and the heart that pumps blood throughout the body
12. The variables of frequency, intensity, time, and type
14. The ability of a muscle or muscles to push or pull with total force
15. gradual increase in one or more of the FITT variables to create an overload
17. The combination of fat mass to fat free mass
18. Smallest of the blood vessels and the place where tissues of the body exchange carbon dioxide in exchange for oxygen
19. The muscles' ability to move a joint through its full range of motion
20. Exercise training is specific to the muscles to the muscles used and the components of fitness trained

1. An increase in one or more of the FITT variables to provide an additional workload
2. Number of exercise sessions per week
3. Ability of the heart, blood, blood vessels, and lungs to supply enough oxygen to the body during long periods of physical activity
4. A result that can be achieved in 6 months or more
8. The ability of muscles to work over a long period of time without becoming tired
9. Minutes of repetition
13. Small tubes or vessles for blood leaving the heart
