Establishing a good solid base is critical. Legs need to be braced open wide to keep your center of gravity low. Wrestlers should be warming up with exercises that focus on flexibility to effectively execute down positions. Tucking your toes under while positioning increases mobility and quickness while preventing ankle rides. If a wrestler ends up on his stomach in a bad defensive position they should not try to get up using the arms.
Arms are weaker than a wrestlers legs.
The Hip Heist is a movement drill to teach the concept of weight positioning using agility to shift your weight alternately from your hands and then the feet. The Knee Scoop, Hip Heist and other reversal escape moves should always return to the base position. An effective top stance is trying to achieve two goals. One is to keep the opponent from escaping or preventing them from executing a reversal. The second goal is to control the opponent down to the mat, and turn them over for the pin.
