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.

Calves Over Bench Sit-Ups

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.

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).

Sit-Ups

sit ups

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

Lying on your back with your knees bent. Your feet are on the floor and your hands are behind your head :

  • Inhale and lift your torso rounding your back.

  • Exhale at the end of the movement

  • Back to the starting position but your back shouldn’t touch the floor.

  • Do it again until the burning sensation in your stomack.

This exercise mainly works rectus abdominis and a little bit hip flexors and obliques.

Variants

sit ups

sit ups inclined board

  • To make it easier, you can do this exercise with your feet blocked by a partner

  • To make it easier, you can do this exercise with your arms extended forward

  • For more intensity, you can do this exercise with a inclined board

Note

Women generally have less developed bust and proportionately larger legs than men. It’s easier for them to do sit-ups and not take off the feet during the movement.

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.

Seated Machine Hip Abductions

seated machine hip abductions

Sitting on the machine :

  • Force your legs apart as far as possible

When the machine’s seat is inclined, it’s gluteus medius that works. When the machine’s seat is slightly inclined or vertical, it’s the upper part of the gluteus maximus that works. The ideal is to vary the torso’s inclinaison in the same set.

Example

10 reps with your back glued on the machine’s seat and 10 reps with your torso leaning forward.

This exercise is excellent for women because it tone the upper part of the hip. It gives the buttocks a rounded appearance, making the waist look slimmer.

Standing Machine Hip Abduction

standing machine hip abduction gluteus medius

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

Standing on the machine on one leg. The outer side of the other leg is gluted to the pad below the knee joint (close to your ankle) :

  • Raise the leg as high as possible and slowly return to the starting position by controlling the movement.

Attention

standing machine hip abduction gluteus minimus

Abduction is limited because the femur’s neck is quickly bumping on the edge of the cotyloid cavity.

This exercise works gluteus medius and gluteus maximus. For best results, it’s advisable to work with high reps.

Individual Variations In Hip Mobility

hip mobility

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

Without taking into account the individual differences in muscle elasticity and ligament laxity, it’s bone shape of the hip joint that determines the main variation in hip mobility.

It’s mainly in the amplitude of hip abduction that bone configuration plays an important role.

Examples

  • An almost horizontal femoral neck (coxo vara) with an upper edge of the important cotyloid cavity and covering, will limit abduction movements.

  • An almost vertical femoral neck (coxa valga) with an upper edge of the less important cotyloid cavity will facilitate abduction movements.

This means that it is useless to raise the leg very high laterally if the morphology doesn’t allow it.

Attention

If someone forces the hip’s abductions, femur’s neck will bump on the cotyloid cavity edge. And this person will compensate the lateral raise of the leg with a pelvic tilt on the femur head of the other leg. It should be added that forcing oneself to make abduction sets may, over time, create microtraumas in some people that will cause excessive development of the cotyloid cavity upper edge. This has the consequence of limiting the hip’s mobility and creating painful inflammations.
