Hanging Leg Raises

hanging leg raises

What’s up ? This is THE stephane ANDRE ! I read a Frederic Delavier’s book « Strength Training Anatomy » and I learned good stuff.

Suspended on a chin-up bar :

  • Inhale and back up your knees as high as possible by approaching your knees to your torso.

  • Exhale at the end of the movement

This exercise works :

  • The iliopsoas, rectus femoris, tensor fasciae latae when you raise your legs.

  • The rectus abdominis and a little less obliques work when you move your knees to your torso.

To target the work on abs, it’s advisable to make small oscillations of thighs without never having the knees below the horizontal.

Attention

Rotations of the torso to the machine are proscribed for people suffering from low back or having already had a herniated disc.

Variant

hanging leg raises variant

By raising your knees on the side alternately to the right and to the left, obliques work more intensely.

Abdominal lumbar balance

It’s necessary to work in a balanced way the abdominal’s muscles and the back’s muscles (erector spinae). A lack of tone of hypertonicity of one of these two muscle groups can create a bad posture, and over time, create pathologies.

Example

Hypertonicity of the lower part of the erector spinae (sacro lumbar mass) with a hypotonicity of the muscles of the abdomen, will create a hyperlordosis with an abdominal ptosis. This postural defect can sometimes (if it is taken in time) be diminished by exercises of reinforcement of the abdominal muscles.

Conversely, hypertonicity of the abdominal muscles with loosening (hypotonicity) of the erectors spinae, especially in the upper part (multifidus spinae, longissimus, iliocostalis), will create a kyphosis (rounding back ) with loss of lumbar vertebral arch. This postural defect can sometimes (if it taken in time) be diminished by exercises of reinforcement of erectors spinae muscles.

Leg Raises

leg raises

What’s up ? This is THE stephane ANDRE ! I read a Frederic Delavier’s book « Strength Training Anatomy » and I learned good stuff.

On your elbows with your back on the backrest :

  • Inhale and back up your knees to your torso by rounding your back to feel your abs contraction.

  • Exhale at the end of the movement.

This exercise works the hips flexors, mainly iliopsoas, obliques and rectus abdominis (it’s the inferior part of the rectus abdominis which works intensely).

action iliopsoas muscle

Variant

  1. To target the work on abs, it’s advisable to make small swings of legs with your rounded back, without ever lowering your knees below the horizontal.

  2. To increase the intensity, the movement can be done with your legs stretched but it’s necessary to have a good hamstrings flexibility.

  3. You can keep your knees grouped to your torso for a few seconds to have an isometric contraction.

Incline Leg Raises

incline leg raises

I read a Frederic Delavier’s book « Strength Training Anatomy » and I learned good stuff.

Lying on the incline bench with your hands gripping the handles :

  • Raise your legs up to the horizontal

  • Raise your pelvis by rounding your spine to try to touch your head with your knees

This exercise works your muscles in 2 phases :

  1. When you raise your legs, it’s iliopsoas, rectus femoris and tensor fasciae latae that work.

  2. When you round your back, it’s your abs, mainly the part under your navel of the rectus abdominis that work.

Note

This exercise is great for people who have difficulty to feel the work on abs. As this movement is difficult, it’s advisable for beginners to adjust the bench with a low inclination.

Specific Bench Sit-Ups

I read a Frederic Delavier’s book « Strength Training Anatomy » and I learned good stuff.

Your feet wedged under the pads with your torso in the void and your hands next to each ear :

  • Inhale and raise your torso to try to touch your knees with your head rounding your spine.

  • Exhale at the end of the movement.

This exercise is excellent for working rectus abdominis and a little bit your obliques. It’s good to know that during anteversion of your pelvis, iliopsoas, rectus femoris and tensor fasciae latae are strongly solicited.

Note

This movement requires good power in abs. It’s necessary to do exercise easier before to gain this power.

Incline Bench Sit-Ups

incline bench sit ups

I read a Frederic Delavier’s book « Strength Training Anatomy » and I learned good stuff.

Sitting on the bench with your feet under the pads and your hands behind your neck. Inhale and tilt your torso without ever exceeding 20° :

  • Move your torso back up by slightly rounding your back to better target the effort on recuts abdominis

 

  • Exhale at the end of the movement.

This exercise work the entire rectus abdominis muscles and iliopsoas, rectus femoris and tensor fasciae latae (these last 3 muscles help pelvis anteversion). This movement is to do with high sets.

Variant

incline bench sit ups

When you back up, you can do a rotation of your torso to transfer a part of the effort to the obliques.

Example

A rotation to the left work more intensely right abdominal external oblique, left abdominal internal oblique and rectus abdominis on the right. Twists can be done alternately or unilaterally. The goal is to focus on the muscular sensation and it’s unnecessary to incline the bench too much.

  1. Rectus abdominis

  2. Abdominal external oblique

  3. Abdominal internal oblique

  4. Transverse abdominal

With quadrupeds, the entire rectus abdominis muscles passively support the viscera (like a hammock ) and help a little in locomotion.

With human being in bipedal mode, the entire rectus abdominis muscles have hugely strengthened so that the torso and pelvis is upright and prevent the pelvis from tipping excessively during walking or running. They became powerful muscles of contention and they built a strong core to maintain viscera in an active way.

Calves Over Bench Sit-Ups

I read a Frederic Delavier’s book « Strength Training Anatomy » and I learned good stuff.

Your legs are on a bench with your back to the floor and your hands behind your head :

  • Inhale and raise your torso as high as possible to touch your knees with your head by rounding your spine.

  • Exhale at the end of the movement.

bench sit ups

This exercise works recuts abdominis and more intensely the parts above the navel.

It’s good to know that farther is your torso from the bench, this increases the mobility of the pelvis. This allows a greater range of motion and works more flexors muscles of the hips (iliopsoas, rectus femoris and tensor fasciae latae).

Gym Ladder Sit-Ups

Hook you feet in the gym ladder with your thighs vertically. Your back to the floor and your hands behind your head :

  • Inhale and raise your torso as high as possible by rounding your spine.

  • Exhale at the end of the movement.

This exercise mainly works rectus abdominis and a little bit internal and external obliques.
