Dumbbells can provide the two types of overload that lead to muscle growth: mechanic and metabolic. Mechanic overlead is the result of damaged caused by muscle contractions, which stimulates the repair process and leads to an increase in muscle size. Metabolic overload occurs when a muscle is worked to fatigue, which leads to the adaptation of muscle cells being able to store more glycogen which can cause muscles to increase in size. Heavy dumbbells can generate mechanical overload, while moderate-weight dumbbells combined with high reps (to fatigue) can produce metabolic overload.
