Gym Dumbbells are divided into two categories:
Composable or Adjustable Dumbbells; they offer the possibility to load the dumbbell with the weight you want, via the discs.
Saving you money, but losing time when changing discs.
Fixed Weight Dumbbells; dumbbells and discs are fused, so they cannot be changed.
The advantage is that they are immediately available for use, do not have to be mounted and there is no risk of the discs falling off.
The disadvantage is that they force the athlete to buy new dumbbells every time a different weight is desired.
Whatever choice you make, dumbbells are an essential ally for your workout-training.
They help to develop strength and muscle mass faster.
Essential for achieving defined biceps and triceps, both in home gyms and professional gyms.
