Army Physical Readiness Training (PRT) Practice Test

In the Forward Lunge exercise, the appropriate action for the rear knee is to bend but not make contact with the ground. This position ensures that the lunge is performed with proper form and stability, minimizing the risk of injury and maximizing the effectiveness of the movement. When the rear knee bends, it allows for greater depth in the lunge and improves balance by distributing weight more evenly between both legs. Keeping the rear knee off the ground prevents unnecessary strain on the joint and maintains the correct alignment of the hips, knees, and torso. Bending the rear knee also engages the muscles effectively, including the quadriceps, hamstrings, and glutes. This engagement is crucial for building strength and improving overall athletic performance. Proper technique is essential in any exercise, and in the case of the Forward Lunge, maintaining the rear knee elevated while bending helps achieve this goal.
