In this world of sophistication in which we live, some looks towards simplicity are inevitable. In the field of bodybuilding and strength, the contrast between the new and the classical occurs in intensive.
At the doors of sports centres are advertised new arrangements every six months or less, as if necessary to replace procedure every so often. In the gyms they share space equipment sophisticated with classic cufflinks. But, what you offer hand weights to keep as a valid option?.
As much as we try to separate muscle functions in segments and parts to carry out systematic training, the anatomical reality tells us that the movements are global and the performance muscle is combined and orchestrated.
In this context, the use of cufflinks offers something unique: the freedom of movement. We can combine in a gesture only, as for example in a lift the dumbbell exercise from the area of the hip until vertical arm: muscle activity of the forearm (stabilizing the wrist and putting grip), biceps (in elbow flexion), deltoid (in the separation of the shoulder), pectoral (in the stabilization of the shoulder) and triceps (to lowering the dumbbell steadily with elbow flexion).
But here comes an apparent contradiction: the simplicity of the dumbbell element requires a great complexity in the gesture of the movement. Small variations of the gesture will give wealth to muscle action, but may also take away efficiency to the activity or even desesquilibrar exercise (e.g. muscle more than the other arm).
