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.

machine trunk rotation abs

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.

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.

Dumbbell Side Bends

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

Standing wit your legs slightly apart with one hand behind your head and a dumbbell in the other hand :

  • Do a lateral flexion of your torso on the opposite side of the dumbbell

  • Return to the start position or go beyond it by doing a passive flexion of your torso.

  • Alter the sets by changing the dumbbell aside without recovery time.

This exercise works mainly on the flexion side obliques and a little bit rectus abdominis, deep muscles of the back and quadratus lumborum.

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.

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.
