The incline dumbbell curl is a variation of the dumbbell curl and an exercise used to build bigger biceps.
The biceps is a tricky (and fun) muscle to target and putting yourself in various degrees of incline can help manipulate the range of motion for either a tighter contraction or deeper stretch.
The incline dumbbell curl elongates the negative portion of the dumbbell curl, creating a deeper stretch on the biceps muscle tissue.
Dumbbell curl variations are primarily popular among lifters looking to improve their aesthetics as direct arm work will have limited carry over into maximum strength.
