Although my dumbbell workouts differ, a common factor of each is a the “curling’ motion”, where the dumbbell weight is moved through an arc with the focus of primarily using the strength of the bicep muscle. The variation of bicep curls using dumbbells are all contracted to lift the weight upward through the arc, to a point where you feel the pump at its peak. Its important not to over-curl or over-extend while doing a repetition. It is also important to always breathe in a rhythm and consistency. When you train your body always practice correct form and good control. Each repetition to any bicep workout should be done inhaling on the way down when releasing and exhaling when you force on the way up when performing the curl.This contraction and extension together constitute a single repetition.
