Dumbbells

The dumbbell is a strength training accessory used for free weight training that is composed of a bar and an equal weight at each end. The work you can carry out with a dumbbell is very similar to that of a bar with weights; the difference is that with the bar you can only work with the two arms at the same time, and with the dumbbell you can also work with only one arm and, in this way, focus the exercises more. Dumbbells are available in different weights, materials and shapes.
