In physical training the most important thing is to perform muscle movement with the greatest possible control to achieve the best results and above all not suffer injuries in the middle of the routine.
When we train with high weights or we are not able to perform certain routine in the gym we tend to perform a pendular movement to help us with other muscles that we want to work with, which cause less stress, less muscle damage and above all a lesser development, it is very important you know how to perform the training well or consult a coach to receive personality help, remember that it is not good to sacrifice muscle control by weight.
There are many people who train in the gym who like to draw attention lifting large weights, this to receive the attention of people around them, but not everything depends on the weight we can lift, but the weight we can control and perform the exercise in the best possible way, I imagine that they once observed a person who wants to attract attention lifting a lot of weight but nevertheless appears to be weak and thin unlike another who appears to be very strong and toned lifting not so high weights.
The big difference between the people who train doing the pendular movement and those who do thinking or mentalizing control, are the final results, therefore it is better to perform the routine in the best way possible without trying to draw the attention of others people from the gym.
Nose really if this movement is called pendular, but they are the most appropriate words I found and I decided to baptize this movement as pendular, where for example when we perform Biceps we receive a help from the hips and back this to be able to lift a very heavy weight. elevated, take into account that the best weight for development is that which allows you to perform between 8 and 12 repetitions in each series.
Many people even take an impulse before performing the respective repetition and drop the weight, I remember that the movement has to be controlled both in the contraction part and muscular elongation, that is to say controlling the movement when going up and down usually in all the range of the muscle, I mean moving the muscle from beginning to end, from its most elongated point to the point where you can not contract more because another muscle or joint does not allow it.
I am currently working on the development of 3D animated characters that will allow a broader understanding of what I mean, but if they were in the gym for some time I am sure that they saw several people performing the movement in an inappropriate way.
When we work the muscles it is best to isolate them and perform the exercise with the greatest control and therefore reach their limit without involving other muscle groups or involve them as little as possible, that is if today we work triceps do not have to involve muscles from the back in the exercise, I mean to get involved directly because indirectly in one way or another other muscles are involved because our bodies are a complete system and everything is integrated in one way or another we exercise muscles indirectly .
The abdominals for example have to have a very good control because it is very easy to drop the weight of an abdominal plate on the spine or on the shoulders and end up fatigued or tired on all sides except the abdominal muscle.
Thank you very much friends I hope this information is useful, I hope your comments and suggestions as well as the experience in this amazing fitness world, regards.
