Machine Trunk Rotation

machine trunk rotation abs

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

Attention

Torso’s rotation in the machine are proscribed for people suffering from lower back or having already had a herniated disc, as they might aggravate or reappear this lumbar pathology.

Standing on the turntable with your hands on the handles :

  • Rotate your pelvis from one side to the other, keeping your shoulders fixed and controlling the rotation. Your knees are slightly bent to avoid the risk of ligament stretching.

This exercise works mainly external and internal obliques and a little less rectus abdominis. Sets with high reps give better results.

Broomstick Twists

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.

General Stretching Of The Upper Body

stretching upper body

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

Stand with your feet a little wider than your pelvis width and you back is straight :

  • Hold your ams vertically with your hands clasped and your fingers crossed. Your palms directed upwards :

  • Inhale to inflate your lungs to the maximum and stretch your intercostal muscles. Push your palms up keeping your back and head upright.

  • Exhale slowly by relaxing and starts again.

This stretching exercise stretches intercostal, rectus abdominis, latissimus dorsi, teres major, triceps. When you incline your torso laterally, you stretch more your external oblique and internal oblique, quadratus lumborum and the internal and medium part of your erectors spinae.

stretching upper body lateral

Note

This stretch is great for relaxing the body after a training with heavyweights like leg press, squat, deadlift because the ribcage and spine have been compressed.

This movement may occasionally replace or supplement the stretching at the bar  to rebalance the pressure and tensions of the intervertebral joints.

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.

Abs Stretching

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 ».

Specific Bench Sit-Ups

specific bench sit up

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.
