The term second base only applies when doing a one legged stunt, this position can also be considered a side base. The secondary bases help lift the flyer up into the air and support the flyer foot. The hand position for the side base can vary depending on preference. The more common placement, which is also more reliable and sturdy, is to have one hand under the middle of the foot and the other hand pushing up on the wrist of the main base to lift from underneath. The other approach is to have one hand under the middle of the foot and the other hand on top of the foot for stability. The problem with keeping the hand on top of the stunt is that the side base can tend to push down on the stunt instead of pulling up because they might not be as tall as the rest of the stunt to get their hand on top enough, which can create extra weight for the other cheerleaders on the bottom of the stunt. The second base hand positioning functions to lift and to stabilize the flyer foot from shifting from side to side.
