Roman Chair Side Bends

roman chair side bends, abs

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

This exercise is working on the bench originally planned for lumbar extension.

Put yourself on the side with your hip on the bench and your torso in the void. Your hands are behind your head or on your torso and your feet are wedged under the pads :

  • Do a lateral flexion of your torso upwards.

This movement works mainly obliques and rectus abdominis on the side of flexion. But obliques and rectus abdominis on the opposite side also works by making static contraction (isometric contraction) to prevent your torso from falling below the horizontal.

Note

During the lateral flexions of your torso, quadratus lumborum muscle works always.

Broomstick Twists

broomstick twist

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

Standing with your legs apart and the stick placed on your trapezius above your posterior deltoids. Your hands are on the stick but don’t press on it :

Make a torso rotation on one side then the other, keeping your pelvis motionless with an isometric contraction of your glutes.

This exercise works when your right shoulder is forward : the right external oblique, left internal oblique and a little bit rectus abdominis, quadratus lumborum and extensor spinae on the left side.

For more intensity, it’s possible to slightly round your back. A variant is to do this movement sitting on a bench, which will block your pelvis and focus the effort on your abs.

It’s with sets of several minutes that you get the best results.

Attention

Torso rotations are prohibited for people suffering from low back or having had a herniated disc as this may aggravate or resurgence of this lumbar pathology.

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.

Abs Stretching

abs stretching anatomy

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

Lying on your stomach on your hands with your arms extended :

  • Straighten up your chest slowly by tilting your head back slightly

  • Maintain this position for few seconds while breathing slowly to feel the stretching of your abs.

Variant

It’s possible to make this movement with your hands on a bench and your feet on the floor, or you’re lying on your back on a big ball (Swissball).

Note

Stretching of abs can be an important element in some sports like throwing sports, especially the javelin. In this type of sports, it’s essential to have good flexibility and a good abdominal amplitude to make the movement perfectly.

Attention

Abs stretching are to be avoided in case of lumbar pathology.

Note

The position tilted forward (anteversion) of women’s pelvis allows a portion of the child’s weight to be transferred to the abs. By analogy, abs muscles can be compared to a « hammock ».

Good Position For Abs

Action on lumbar curvature of the psoas muscle

Psoas muscles have other functions than to be powerful flexors of hip. They put the lumbar spine in lordosis, which increases the arch.

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

Abs exercises (especially for rectus abdominis) must work with the round back (round your spine). It’s the opposite of other exercises.

For vertebral coil exercises, the mechanicals stresses on vertebral joints aren’t the same as for exercises such as squat, deadlift and other exercises with weight. For example, for squat, the spine isn’t arched at the lumbar level. The vertical pressure with the spine’s rounding pushes the nucleus pulposus intervertebral disc backwards, which can compress nerve elements and create sciatic herniated disc.

For abs exercises, it’s the opposite. If during the abs execution you forget to round your back with an intense contraction of abs and obliques, the powerful flexors of hips (psoas major) will increase the lumbar arch. This will move the intervertebral discs forward as they aren’t stabilized by the vertical pressure. Then an excess of pressure at the back of the lumbar vertebral joints can create lumbago or more serious, joints damage by compression and shear.

Stretching Of Glutes

stretching glutes

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

Sitting on the floor with one leg stretched out and the other leg bent with your foot on the floor and moving from the outer side of your leg stretched. Press on the outer side of your knee bent with your opposite elbow. This exercise mainly stretches the muscles of the gluteus maximus and the lateral rotator group (piriformis, gemellus superior, obturator internus, gemellus inferior, quadratus femoris and obturator externus).

Variant

It’s possible to press on your knee with your 2 hands.

Good Morning

good morning leg exercise

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

Standing with your feet slightly apart. The barbell put on your trapezius or lower on your posterior deltoids :

  1. Inhale and bend you torso forward to the horizontal with your back straight, the axis of flexion passing through coxofemoral joint.

  2. Back to the start position and exhale.

It’s possible to make the movement easier by bending your knees.

This exercise works glutes (gluteus maximus), all spinal muscles and hamstrings (except the biceps femoris short head). Besides the knees flexion, hamstrings have the function of retroversion of the pelvis, which allows to straighten the torso. This action performed when the torso bound by isometic contraction to abs and sacro-lumbar muscles.

To have better feeling on hamstrings, it’s advisable never to work with heavy weight. In negative phase, « good morning » is excellent for stretching the back of the thighs. Work regularly the negative phase of the « good morining » helps prevent injuries to hamstrings during the squat with heavy weight.

good morning leg exercise method straight bent leg

  1. Legs stretched while your torso leans forward, extends hamstrings. This make is easier to feel sensations of hamstrings when you straighten up your torso.

  2. Legs bent while your torso leans forward, relax hamstrings. This facilitates flexion of hip.
