Definition

Health
The state of emotional, physical and social well-being.
Heart rate
Number of heart beats per minute.
Hydration
Having the appropriate level of water in the body for it to function optimally. When this level of water falls below optimal levels it is referred to as dehydration.
Hypertrophy
The increase in size of skeletal or cardiac muscle.
Circuit Training

A waste product produced in the muscle tissues during strenuous exercise where the anaerobic energy system is in use.
1st Class Lever
1st Class: A lever in which the fulcrum is positioned between the load and the effort.
2nd Class Lever
2nd Class: A class 2 lever has the load and the effort on the same side of the fulcrum, with the load nearer the fulcrum.
