If you have been patient enough to read, you will have learned that hip and ankle stability are the foundation of most successful athlete’s and individuals doing hard things. Force comes from the ground up. Muscle activation through sensory adaptation and brain signaling obviously comes from the top down. Thus, if we can create stable hips, ankles, and feet, then those signals performed during velocity training are faster, more efficient, and more athletic. The Copenhagen plank strengthens the adductor muscles, creates core stability by using an elevated surface such as a bench or box shown here. The higher the surface, the harder it is to keep yourself in ideal extension. These type of frontal plane stability warm ups are great to take stress away from the knees and hips and back into the glutes and quads. Try 2 sets of 12 each side before athletic development or sport play.
