Which is a single-leg exercise included in knee injury prevention programs?

• A. Lunges
• B. DL squat
• C. SL Squat
• D. Prone Plank

Answer: (C)

The key idea is training unilateral knee stability and proper knee tracking to prevent injuries. A single-leg squat places the entire load on one leg, so you must control hip stability, knee alignment, and trunk position throughout the movement. This intensely challenges neuromuscular control around the knee, helping to prevent valgus collapse and improve dynamic knee stability during real-world tasks like landing, cutting, or changing direction. Because you’re balancing on one leg, you also train the hip muscles (especially the gluteus medius) to keep the knee from collapsing inward, while the quadriceps and hamstrings work together eccentrically as you descend and concentrically as you rise. The movement is scalable—depth, tempo, or a light resistance can be added as strength and control improve—making it a staple in knee injury prevention programs. Lunges, while unilateral, involve a forward step and a different loading pattern that may not challenge single-leg knee control to the same extent. The deadlift/squat variant typically uses both legs, reducing the emphasis on single-leg stability. A prone plank targets core stability rather than knee mechanics.
