(A) Plank Tricep Extension

Start from an elbow plank position. Brace your core hard and drive your hands into the ground until you are up on your hands in a push up position. With a continued core brace lower yourself down back to your elbows. That’s 1 rep. Now repeat until your arms and core are fatigued. Remember, this is an advanced move so be sure you can maintain a good strong core brace through the entirety of the movement.
