Rock hard abs don't come from sit-ups alone. Incorporate more intense exercises, such as the hanging leg raise to challenge your entire core.

The hanging leg raise works the entire midsection, with particular emphasis on your hip flexors and the lower portion of your abdominals.

How To: Hanging Leg Raise

To perform the hanging leg raise, hold onto a fixed pull-up bar with your arms and legs extended. With your legs together, contract your abdominal muscles and lift your knees as high as possible by rolling up your spine and bringing your pubis toward your sternum. Slowly lower your legs to return to the starting position. Hold a dumbbell between your feet to increase the difficulty of the exercise.

Core Muscles Worked

The hanging leg raise requires flexion and extension of your torso. This activates the fronts of your hips, but also the six-pack muscles of your middle.

Iliopsoas

The iliopsoas is composed of two muscles -- the iliacus and the psoas major. These muscles, also known as the hip flexors, are the prime movers for flexing the thigh and flexing the trunk. The iliopsoas is the primary muscle worked during a hanging leg raise.

Rectus Femoris

The rectus femoris the is one of the four quadriceps muscles. It is the most superficial muscle in the middle of the front of the thigh. This muscle works with the iliopsoas to flex the hips during a leg raise. The rectus femoris also crosses the knee joint and assists the other quadriceps muscles in extending the knee.

Tensor Fascia Latae

The tensor fascia latae assists the iliopsoas and rectus femoris muscles during hip flexion. The muscle is located on the upper lateral thigh and is enclosed between layers of connective tissue known as fascia.

Adductors

The adductors are a group of muscles located on the inner thighs and consist of the adductor magnus, adductor longus and adductor brevis. These muscles along with the pectineus work to press the thighs together as you raise your legs.

Rectus Abdominis

The rectus abdominis are the most superficial of the abdomen -- forming the enviable six-pack in lean athletes. The muscles flex and rotate the lower back and stabilize the pelvis during walking. The rectus abdominis muscles are not engaged during a hanging leg raise until your knees rise above hip level and your pubis lifts toward your chest.

Obliques

The external and internal obliques are worked, to some extent, once your knees reach horizontal when performing a hanging leg raise. When the obliques work individually, they aid the muscles of the back in trunk rotation and lateral flexion -- or bending side to side.

A variation of the hanging leg raise that puts more emphasis on your obliques has you alternately raise your legs to the left and right, rather than straight to the front.

Secondary Muscles

The muscles of your forearms, shoulders and back are used to grasp the bar, support your weight and stabilize your back and shoulder joints when you perform hanging leg raises.
