Knock knees is the slang term used for "genu valgum" — an inward angle of the thighs when a squat is performed or while standing in a neutral position. This deformity is typically caused by weak abductor muscles, which are found on the outsides of the hips and thighs.

To correct this problem, do abductor-strengthening exercises. The muscles involved with abduction are the gluteus maximus, gluteus medius, gluteus minimus and tensor fascia lata.

1. Side Lunges

Side lunges work your abductors, hamstrings and quadriceps.

HOW TO DO IT: Stand with your feet hip-width apart and your arms in front of your chest. In a steady motion, take a big step laterally to your left. When your foot comes to the ground, bend your knee, and push your butt backward.

When you feel a strong contraction on your hip and other thigh, stand up, bring your feet back together and repeat to the other side. Continue to go back and forth for 10 to 12 repetitions. If you want more resistance, hold a medicine ball in front of your chest.

2. Side Step-ups

Side step-ups require the use of a weight bench or chair.

HOW TO DO IT: Stand with your right side facing the bench and your arms in front of your chest. In a steady motion, place your right foot on the bench, press down and lift your body in the air.

When your right leg is straight, hold for a second, lower yourself and repeat. After doing 10 to 12 reps, switch sides. As with side lunges, hold a medicine ball for added resistance.
