The phosphagen system runs on ATP and creatine phosphate stored in the muscle and is largely exhausted after roughly 10 seconds of all-out effort, which is why it powers sprints and single lifts.

Which warm-up technique moves joints through their range of motion, mimicking the coming activity?

Dynamic stretching moves joints through their full range with controlled movements such as leg swings and walking lunges; long static holds before exercise can temporarily cut strength, so a dynamic warm-up is preferred.
