From Pathfinder Wiki
There are two purposes for warming up before exercising. The first is that it stretches and warms the muscles, decreasing the likelihood of an injury. The second is that it gradually increases the heart rate in preparation for the workout. Warming up can be as easy as doing leg stretches for a few minutes. Slowly warming up can help people do even more aerobic exercise than if they had not warmed up at all.
