Static flexibility tests are more common than dynamic tests because they are easier to replicate. It is difficult to standardize motion-based tests between different subjects, while static tests are simple and easy to standardize because the metrics are fixed and not open to interpretation.

The controlled movement of limbs through a full range of motion reduces muscle tightness and increases the range of motion of those particular muscles. By going through dynamic stretching of muscles that are going to be used in an activity, the body is prepared for that specific activity. When muscles are loose and relaxed for an activity, it reduces the risk of injury, as well as muscle soreness and fatigue.

In order to accurately evaluate progress in a flexibility workout regimen, it is important to establish a baseline level of flexibility and then to track progress during the regimen from that starting point. A baseline establishes where an individual is before starting a program; without a baseline, it would be difficult to know how much progress has been made as a result of the workout regimen. Tracking progress during a regimen is important because that information establishes the effectiveness of the regimen.

Both types of hurdle stretches loosen up the hamstring in the same way. But the hurdle stretch with the leg pointed back puts sideways torque on the back knee and can result in injury. So while the potential benefit of the exercises are the same, one risks serious injury to the knee.

Both progression and overload are concerned with slowly increasing the intensity and challenge of the exercises of a workout. Overload arises from the need to increase exercise intensity to maintain a challenging workout: as a body adapts to a given exercise level, the difficulty must be increased to keep challenging the body and making progress. Progression is closely related to overload and also requires that an exercise program gradually become more difficult. Progression, however, is focused on the increased goals of an exercise program rather than the adaptation of the human body.

Both static and passive stretching are similar in that limbs are moved into and held in a stretch position. In static stretching, a person actively holds their own limbs in the position, while in passive stretching, a partner moves and holds limbs in the stretch position for the other person.
