Developing and maintaining it are important parts of a fitness program. Good flexibility can help a soldier accomplish such physical tasks as lifting, loading, climbing, parachuting, running, and rappelling with greater efficiency and less risk of injury. Flexibility refers to the range of movement of a joint.
Flexibility is the range of movement of a joint or series of joints and their associated muscles.
It involves the ability to move a part of the body through the full range of motion allowed by normal, disease-free joints. No one test can measure total-body flexibility. However, field tests can be used to assess flexibility in the hamstring and low-back areas. These areas are commonly susceptible to injury due, in part, to loss of flexibility. A simple toe-touch test can be used.
