In order to safely manage the stunts, cheerleaders need muscular strength. Attempting to lift this amount of weight could be very dangerous if the person lacks physical strength. Females as well need muscular strength. Partner stunts require two people pushing simultaneously. If a female doesn't have above average strength, she can endanger herself and others.
Strength is a major factor to the safety of cheerleading and injury prevention.
The safest jumps are those that start and land with both feet and knees together. Individuals without a good vertical jump cannot land on two feet, resulting in twisted ankles and other leg injuries. Jumping is also important so that the flyers' can better help their partners in stunts. The vertical jump of the female has a direct effect in the strength required of the male cheerleader, the safety of the stunt, and the level of difficulty the couple can achieve. Pyramids require males to stand in a wide stance and advanced partner stunts sometimes require females to extend one leg above their head.
