The incline dumbbell biceps curl develops size and strength in the biceps and forearms. The incline angle places more resistance on the lower portion of the bicep. The incline dumbbell curl is an alternative exercise to the traditional seated alternate curl.A favourite biceps builder amongst body builders, this exercise primarily works the biceps with the front shoulders and forearms acting as secondary muscles.
The important thing to remember about this exercise is to keep your back flat on the bench and not to involve your shoulders too much. Remember to keep your feet flat on the floor.
