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

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.

Importance Of Shoulder Straightening

kyphosis

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

We spend several hours sitting in a day. It’s relaxing but it can create a problem. This problem is the Kyphosis which is the rounding of the upper back with shoulder enrolement forwards.

We can have this bad position because of the hypotonicity (decreased muscle tone) of muscles bringing together shoulder blades and external rotator muscles of arms or because of the hypertonicity of torso’s muscles (usually for men, excessive training of chest).

As you know, it’s a bad posture and it’s important to rebalance all that. Exercices that do this are exercice that work posterior deltoid (back of shoulder) like one arm rear deltoid fly with cable, low pulley bent-over lateral raises and others.

Note : For deadlift, the rounding of the upper back limits the power of lifting, that why it’s important to straighten your shoulders to use all your potential.
