Heavy dumbbells will generate mechanical overload. This is where muscles are damaged and the repair process results in growth. Moderate-weight dumbbells combined with high reps produce metabolic overload. This is the fatigue which causes muscle cells to adapt by storing more glycogen hence the growth in muscle size. Dumbbell exercises can also lead to improved intramuscular coordination. In other words, muscles begin to work together for improved stabilisation of the joints. The compact nature of dumbbells and the ability to move them freely means that they can be utilised to create a variety of different movement patterns. You are able to focus on developing one arm or one leg or each limb in turn.
