Angled Leg Press

angled leg press anatomy

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

Warning : Using leg press with heavy weight may cause a displacement in the sacroiliac joint, which can lead to contracture.

angled leg press

Installed in the machine with your back on the back pad and your feet a little apart :

  • Inhale and unlock security. Bend your legs as much as possible to have your thighs on the sides of your ribcage.

  • Back to the starting position and exhale at the end of the movement.

The feet’s position allows you to target certain muscles :

  • Feet low on the plate work primary quadriceps

  • Feet high on the plate work primary glutes and hamstrings.

  • Feet apart on the plate work primary adductors.

This exercise is good for people with back problems and who can’t do squat. Attention, it’s necessary not to take off the glutes of the back pad.

Low Back Pain

 low back pain

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

Audio file :

The most common painful affection of lumbar region is low back pain.

Usually it’s not serious because it’s often due to the cramps to the small paraspinal deep muscles of the back that connect mainly the bony processes of the vertebrae between them.

This happens during an uncontrolled extension or rotation of the spine. When one of these small muscles has an excessive tear or stretch, it contracts right away. The results is that all small neighboring muscles and erector muscles contracting. The back blocks itself and there is a pain but this blocking of the back allows to limit the movements that can aggravate the tear of the small paravertebral deep muscle.

low back pain

This general contraction of the lower back lasts a certain time and disappears most often with the healing of the small paravertebral muscle’s tear. But it’s possible that some people after healing have these contractures localized for several weeks or years.


These back muscles contractures which are generally not severe may accompany more severe vertebral pathologies such as fractures, ligament tears, muscle tear or herniated disc.

Shoulder Stretching

shoulder stretching

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

Standing with an arm to the horizontal. You take your elbow with your opposite hand and you pull slowly on your arm to bring your elbow to the opposite shoulder.

Keep this position for 30 seconds to feel the stretch.

This exercise mainly works the deltoid posterior and lateral. It’s important to do this because the teres minor muscles and infraspinatus, which are external rotator muscles of humerus, often have contractures that can create a functional imbalance of the shoulder. This may be, for example, excessive tendon’s friction of the long portion of the biceps in the bicipital groove of the humerus. And the consequences of these contractures can be inflammatory pathologies

This exercise works a little bit the trapezius middle and lower portion and rhomboid major muscle.

Variant : You can pull the elbow with your opposite arm from below.

Note : For very muscular persons, the arm’s adduction may be hampered by compression of the brachial biceps on the pectoralis major, which will limit the proper stretching of the shoulder.’s posterior.

Stretch Of The Rotator Cuff’s Posterior Muscles

stretch of the rotator cuff posterior muscles

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

Standing with a dumbbell in one hand. You bend your bust forward by holding yourself to a machine (or with a incline bench).

Release your arm and let hang the dumbbell for a minute trying to relax your shoulder.

This exercise stretches your infraspinatus, teres minor muscle, and a little bit your supraspinatus. These muscles are on the posterior side of the scapula.

In bodybuilding, these muscles often contractures and spasms. The consequences are that this can put your shoulder in a bad position and can, over time, create pathologies of wear and tear tendon.

Note : Contratures of spasms of the teres minor muscles and infraspinatus creates an external rotation of the humerus. Which causes an excessive friction of the tendon of the long head of the biceps (in intertubercular furrow of humerus) in the forearm. The consequences are inflammation followed by a rutpture of wear of the tendon.

It’s for this reason that as soon as you have a suspicious contracture, do this stretch to try to relax your muscles.

Shoulder Injury (Part 1)


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

Shoulders injuries are frequent in bodybuilding because we want develop all deltoid muscles. To do this, we must perform a signigicant number of repetition and movements thus multiplying the risk of injury.

It’s worth remembering that, in comparison with the solid hip’s articulation where the femur head is deeply embedded in the pelvic cavity of the pelvis, shoulder’s articulation, which must be very mobile to allow arms to move in all direction, is very little embedded.

Shoulders can thus be defined as a joint to muscular fixation, the maintenance of the humerus head on the scapula’s glenoid cavity is mainly ensured by a complex musculo-tendinous ensemble.

Although in bodybuilding most injuries occur during shoulders training, it’s rare to see this muscle directly injured. The wound are generally much deeper and appear most often during a false movement or after a long wear by friction of tendon structure reinforcing the articular capsule.

While in other sports of violent contact (such American football) or rapid arms movements (such as throwers) can result in serious injuries with dislocations and enven tendon pull. The main lesion observed is what we call subacromial bursitis.

Some people when performing elevated arm movements, such as back press or lateral raise, the supra-spinous tendon is rubbed and compressed between humerus head and osteoligamentous vault formed by the underside of the aromion and the coracoacromial ligament.


shoulder anatomy

The result is an inflammation which generally begins with the synovial bursa, which normally protects the supra-spinous tendon from excessive friction. And it continue by the supra-spinous tendon itself and ends, if this inflammation isn’t treaed, by touching the adjacent tendons of the infraspinatus at the back and the long portion of the biceps at the front.

Arms elevation becomes extremely painful and there may be an irreversible deterioration of the supraspinatus tendon with calcification and sometimes even rutpure. The latter being observed in general only with people over 40 year old.

The space between the humerus and osteoligamentous vault can vary from one individual to another. Some athletes will not be able to lifte their arms laterally without generating excessive friction. These individuals must therefore avoid all back press, lateral raise to high and also when they train back, pulldown behind the neck.

All exercices with barbell for shoulders should be done in front of, with elbows slightly forward. With dumbbells lateral raise, the correct working angle should be sought, the right movement being the one that is realized painless.

It’s interesting to note that for the same shoulder injury all individuals don’t respond in the same way. Some people can perform all sort of arms raise, compressing and sometimes even deteriorating their tendons without ever triggering a painful inflammatory process. Thus, in the course of an examination, some people have discovered a rupture of the supra-spinous muscle’s tendon without ever having complained of any pain.

Another cause of shoulder pain may be due to an imbalance in the distribution of muscle tension around the joint capsule. Recall that the humerus head is firmly held against the scapula’s glenoid cavity by a muscular system with tendons adhering or passing through the articular capsule. This set is composed at the front by the subscapular, a little more on the outside by the long portion of the biceps, above by the supra-spinous and finally at the back by the infraspinatus and the teres major muscle. Spasm, hypertonicity or, on the contrary, a lack of tonicity of one or more of these muscles, can lead to a bad position of the shoulder joint. This bad position will be the cause, during the movements of the arm, of friction likely to generate inflammatory pathologies.

Exemple : A contracture or a spasm of the teres major muscle and infraspinatus will cause an external rotation of the humerus head which will generate during the movements of the arm, friction in the front of the shoulder joint. And with the time can injure the tendon of the long portion of the brachial biceps.

It will therefore be necessary to ensure to train in a balanced way all the muscles of the shoulder avoiding all the exercices where one will feel a discomfort, a pain or a friction.

Note : Hand massage or better with a vibrator, as well as electostimulation, give very good results to diminish and eliminate spasms and contractures of teres major muscle and infraspinatus.
