Soldiers perform all exercises in sequence and in cadence. Additionally, the soldier must perform a forward and backward straddle run, half-squat laterals, forward and backward frog jumps, alternate one-fourth turn jumps and alternate-staggered squat jumps. They include the Y squat, single-leg dead lift, side-to-side knee lift, front kick alternate toe touch and the tuck jump. There are twice as many CD3 exercises than CD1 or CD2 exercises. Motions are powerful, and the soldier uses explosive energy and dexterity to carry out these advanced exercises. Soldiers will find CD3 exercises more difficult and complex, incorporating repeated jumping, landing and changes in body position, which place greater demands on the lower extremities.
