A HAWK beacon (high-intensity activated crosswalk beacon) is a traffic control device used to stop road traffic and allow pedestrians to cross safely. It is officially known as a pedestrian hybrid beacon .
The stop sign is retroreflective and equipped either with red blinking lights above and below the stop legend or with a legend that is illuminated by LEDs.

As the below examples illustrate, exercise intensity is measured in different ways and is defined inconsistently across studies. Forms of continuous exercise may be performed at multiple intensities for different health benefits; for example, long slow distance training can be performed at low or moderate intensities.
High-intensity interval training (HIIT) is a training protocol alternating short periods of intense or explosive anaerobic exercise with brief recovery periods until the point of exhaustion. [1] HIIT involves exercises performed in repeated quick bursts at maximum or near maximal effort with periods of rest or low activity between bouts.
