Dumbbells are small bars with weights on their ends. Working with dumbbells is very similar to the bar. With the rods can normally only work on a bilateral basis, ie with both arms at once. Instead we can work with dumbbells or monolateral to univocal, ie one arm only. This and the differences in weight are most characterizes the differences between exercises with bar and dumbbell exercises. Dumbbell exercises are neither better nor worse than that can be done with machines, rubber bands or weights. Each muscle as the target is a better way of working. For example, if we want to work biceps maximum hypertrophy, we must perform both as a dumbbell exercises with bar and even machine. A classic exercise for the biceps dumbbells is that you can see in the picture, crull dumbbell bicep and thigh support. To do with a high concentration allows us better than anyone else to congest the biceps as a whole. In this case the elbow flexion is performed only the brachialis and biceps brachii, posture and use of the dumbbell it impossible for other muscles or muscle chains assist with flexion movement. Another difference is that in most of these dumbbell exercises are more functional work, this is not an advantage or a disadvantage, just another peculiarity. For example, the chest work bench:. When to operate a machine, the upward and downward movement of the arms is done without movement or front or side rails or chain from the machine fully regulate the movement allowing only abduction or adduction front. When to operate a bar, and descending movement acénsense we add the corrections front, which made the pectorals, triceps and deltoid to keep the vertical bar and chest does not move to the head or legs. And when we perform the same exercise with dumbbells, the movements of the exercise itself we must add the corrections front and side, so that eventually involve many more than the pectoral muscles, triceps and deltoid. This means that when performing dumbbell exercises hands-free, the result is more comprehensive and less specific than a machine or a bar, and exercise more like rubber bands. This less specific form of work is ideal for beginners and young athletes, and in other cases to professional bodybuilder. Everything depends on the objective. But it is clear that for a beginner in bodybuilding, dumbbell work would be more beneficial than working machines, and to assist the development of all muscles of the body.
