Barbell presses on the flat bench or inclined bench
Traumatologically speaking, bench press or incline, barbell or dumbbell presses present the following risk points:
- The wrist should be kept in line with the forearm. It is a common mistake to extend it while pushing. This excessively stresses the tendons with the appearance of inflammation over time. Applies to all pushing exercises. Such as over-the-nape stretches, parallel dips etc. The hand always remains in line with the forearm, it must not be extended dorsally;
- Another common mistake is to bounce the barbell on the chest to give it thrust (ballistic rebound). The risk of acute trauma lies in bruises and, at worst, microfractures;
- The grip can range from narrower to wider than ideal - which sees, with the load on the chest, the forearms perpendicular to the ground. If you are wider you work more on the pectoral, but with an unnatural inclination. If tighter you work more on the triceps, with greater risk of inflammation in the elbow - particularly without adequate heating, epicondylitis and epithrocleitis can arise.
The back can to be arched, to shift the effort mainly on the triceps and central or low bundles of the pectoralis major. It is a common practice in pure strength disciplines, because it allows you to increase loads a lot. In the past it was thought it could be risky, but today it is consolidated that the (healthy) spine does not suffer anything.

Crosses on flat or inclined bench
A wide range of motion is required to properly perform crossovers on a flat or incline bench.
However, the complete eccentric phase places a great deal of stress on the shoulder joint, so that you are required to use loads suited to your possibilities. Therefore, be careful not to misunderstand: it is important that the eccentric phase is taken to the bottom, but it is also important that pain does not occur and do it with suitable loads, descending slowly, not letting the weights "fall" and then abruptly contract (the so-called pre- somatotropic-stimulating stretch is left only to advanced practitioners). Take care to reach the end of the stroke with extreme gradualness as the muscles strengthen and the tendons of the subscapularis, pectoral major and anterior deltoid become flexible. The negative phase must have an amplitude proportional to the degree of training.
Nothing to report particularly for Crosses and Pushes to the Cables and for Croci alla Pectoral Machine.
Dip at Parallel or Push
Parallel or push dips have two potential risks
- As far as the wrist joint is concerned, being a pushing movement, what is mentioned for the bench press is valid, ie the wrist must be kept in line with the forearm to avoid forcing the tendons;
- As regards the shoulder joint, on the other hand, there is the same risk shown in the crosses: in the eccentric phase, in maximum extension, there is a strong stress on the shoulder joint, dislocation is forced. The peak of the descending phase here, as far as the crosses are concerned, is proportional to the muscular development and to the flexibility of the tendons of the deltoid, subscapularis and pectoralis major;
- Also for the elbow what has been said for the bench press is valid.
Also called pushes or presses on the ground, require a movement with the hands in an extended position with respect to the forearm, so avoid exacerbating the tension on the wrists as occurs by placing the angle between humerus and torso less than 90 °.
Pull Over with Handlebar or Barbell
The dumbbell or barbell pull-over movement, especially its barbell version, forces the retroposition of the humerus, so it is contraindicated for those with a history of dislocations or congenitally loose rotator cuffs.
To avoid a dislocation or a wear trauma, which can be an inflammation due to the pressure of the humeral head on the tendons and ligaments, the eccentric part is brought to the maximum excursion only if the load is suitable and only if the subject has developed a good musculature. We could say more clearly here, as for the crosses and the parallel thrusts, that the eccentric phase must be increased gradually over the weeks, in proportion to one's muscular development and flexibility. The beginner avoids the point of maximum descent until he is sturdy and flexible enough. It is known, and applies to all exercises, that large loads are potentially harmful even in correct execution, as they place significant stress on tendons, ligaments and capsules. This is why even in powerlifting it goes down to 1-3 repetitions only in the pre-competition, since the shorter the period of maximum stress, the lower the risk of developing injuries.
Extension of the forearms to the vertical pulley or lat machine with hands in pronation
There are two delicate points at risk of trauma to consider in this exercise:
- Extending your forearms does not mean that you should also extend your hands dorsally. These should remain in line with the forearms or slightly flexed throughout the movement. This observation applies to all forearm extension exercises. The traumas that are risked have already been illustrated by me previously. Be careful because it is a widespread error. Clearly at greater risk of injury in the phases of strength and mass;
- If you want to flex your forearms in the eccentric phase beyond 90 °, take care to do this only in the quality / endurance cycles, when using a low load and high repetitions. The reasons are the same as mentioned for the leg extensors on the thigh in the squat movement. In fact, the extensions starting from an angle lower than 90 ° particularly stress the tendons that pass through the elbow joint with the risk, among other things, of inflammation in this area due to prolonged rubbing;
Extension of the forearms to the vertical pulley or lat machine with hands in supination
See point 2 of the previous exercise, also for what concerns its variant with the string.
Also known as EZ Barbell Forearm Extension on Bench. The two points mentioned in the extensions to the lat machine are valid, and to these I add:
Correct execution is often distorted by making it hybrid with pull overs. Practically the unwary helps in lifting the barbell by assisting with the powerful sagittal extensors of the humerus. Therefore, in addition to the extension of the forearms, it is accompanied by an impetus given by the extension of the humeri. This condition allows you to use more load, but also to proportionally increase the risk of injury to points 1 and 2 mentioned in the extension to the lat machine.
Nothing to add onExtension of the Forearms Above the Neck with Dumbbells.
Push-ups between the benches
The delicate points are always the same at the wrist and elbow. Since in this case the wrists are forced to stay extended, the risk of injury in these areas is more sensitive than in other triceps exercises. In fact, in the other cases it was possible to gloss over the problem by improving the executive form; here the only precaution lies in "listening to one's body", in moving with concentration, slowness and control.
Another point at risk is the shoulder joint, for the same reasons mentioned in the parallel thrusts: the retroposition of the humerus poses, in the complete descent phase, a luxating stimulus clearly contraindicated in those with a history of dislocation, rotator cuff lax. Even for those with healthy shoulders, this movement must be performed with extreme caution, making the amplitude of the descending phase proportional to the degree of training (practically it must be accentuated as you train). Penalty for the unwary: the risk of inflammation.
For the wrist joint, see the same observation made for the lat machine execution.
