How to avoid lat pulldown and pull-up mistakes.
Some people actually think that these technique errors represent the correct form of exercise execution. They are wrong. Find out why.
Mistake: Pulling too far
Both beginners and experienced exercisers try to pull too far when performing vertical pulling exercises such as lat pulldowns or pull-ups. Instead of trying to touch the chest with the bar or move the chin over the bar (both of which can produce dysfunctional mechanics), the goal should be to achieve proper activation of the upper back and latissimus. This requires several components.
1. ensure sufficient extension of the spine.
This is especially true in the contracted position and helps to center the shoulder joint. A lack of extension of the spine promotes a very unstable shoulder joint and allows for excessive range of motion and faulty mechanics. This is one of the main reasons why many exercisers touch their chest with the bar when performing pull-ups or lat pull-downs. This is in no way a sign of good mobility or great strength, but rather a sign of faulty activation patterns and a dysfunctional movement.
2. pull towards the sternum
Another important tip that promotes ideal vertical pulling mechanics is to pull towards the sternum and not the clavicle. Pulling toward the clavicle minimizes activation of the latissimus and especially the lower latissimus, as the shoulder and scapula cannot be fully moved down and rotated medially toward the spine. Pulling towards the sternum, on the other hand, not only places the shoulders in the best biomechanical position, but also requires a surprising amount of latissimus activation regardless of the weight used. A hint that can be helpful is to imagine that you are pulling your body away from the bar instead of towards the bar.
3. the elbows should be pointing straight ahead.
Rotating the elbows forward is another critical mistake when performing pull-ups and lat pull-downs. Regardless of the grip (overhand, underhand or neutral) or the distance between the hands (wide, medium or narrow), the elbows must point straight ahead instead of to the side. This helps to engage the entire latissimus muscle instead of just the upper portion. It also ensures that you are not pulling from the upper trapezius and shoulders.
4. the bar should NOT touch the chest.
By following this advice, the range of motion of the pull-up or lat pull-down movement will be more compact than most exercisers assume. Correct vertical pulling mechanics during the concentric phase actually end with the bar coming to a stop several centimeters above chest height instead of touching the chest.
By avoiding these mistakes, fast and reliable results can be achieved in a short time. To accelerate the results, personal trainers worldwide recommend using Valhalla Viking Storm before training and the product Teutonic Sword Brothers after the workout.
