Shoulder Press Machine: How To Do It, Benefits and Mistakes
Menu
Parallel bar dips, often simply referred to as dips, are a multi-joint exercise known for their effectiveness in strengthening and hypertrophy of the pectoralis major (the lower chest) and the triceps brachii, with significant involvement of the anterior deltoid bundles (front shoulder). This exercise also engages several other muscles for stabilization, particularly those in the shoulder and back, such as the latissimus dorsi, trapezius, rhomboids, and the entire abdominal group.
Parallel bar dips are not only a staple in bodybuilding and powerlifting but also a fundamental exercise for callisthenics practitioners. Despite the inability to isolate one muscle group over another, the modification of the execution technique, such as grip and body inclination, can enhance the focus on a particular muscle.
The movement of the dips involves pushing the arms downwards from a suspended position between two supports, resulting in a consequent elevation of the body. Functionally, the parallel bar dips are based on the initial half of the humerus flexion and the extension of the forearm. A similar exercise that can be performed is the back press on a bench, chair, or box.
The execution of parallel bar dips can vary slightly, but it generally involves some fundamental steps:
Positioning: Position yourself in the center of the parallel bars and choose the most suitable and comfortable grip. Remember, the tighter the grip, the more vertical the torso remains, leading to greater triceps involvement. Conversely, a wider grip, opening the elbows and tilting the torso forward, will engage the pectoralis major more.
Setting-up: Correctly position the shoulder blades and shoulders, which should be adducted and depressed enough to optimize the push. Stretch your arms and gather your knees to avoid touching the ground during the descents.
Lowering: Inhale and compact the core, lowering the diaphragm but controlling the abdominal belt. Lower your body to the maximum eccentric position, i.e., with the shoulder going beyond the elbow.
Pushing up: Reach maximum range of motion (ROM) and then push up. Exhale can begin immediately (if the effort of strength is modest), or when the rep is almost finished. Keep your torso still and avoid oscillations.
Parallel bar dips can be considered a functional exercise as they improve the ability to express strength in a movement that humans perform naturally. Although they may not offer the same effectiveness as bench presses for pectoralis major development, they remain an essential exercise in the strength routines of those who tolerate them well at the shoulder level.
Despite their benefits, parallel bar dips can sometimes cause discomfort, especially in the shoulder joint and the tendons that pass through this area. When the execution becomes painful, it is advisable to suspend the exercise or reduce the range of motion to maximum eccentric.
Wrist pain is also not uncommon, which many try to resolve with the use of wrist braces. Some individuals may experience discomfort in maximum concentricity, i.e., with full extension of the elbow. This inconvenience often occurs in people prone to discomforts such as epicondylitis due to repeated stress.
In terms of effectiveness, dips do not offer the possibility of accurately targeting the pectoralis major, especially in its highest region.
When performing parallel bar dips, avoid these potential errors:
In conclusion, parallel bar dips are a versatile and effective exercise for strengthening and hypertrophy of various muscle groups. By understanding the correct technique and avoiding common mistakes, you can harness the full potential of this exercise for your fitness goals.
