Dumbbell curls- most important when preforming curls, keep your elbow in a 90 degree angle and fix it in that position when preforming a curl. To intensify the weight distribution lean into which ever side you are curling with, but make sure you never lose the position of the elbow. Bring dumbbell as high as possible and solidify the contraction by holding once bicep is fully engaged for one second. #gym #weightlifting #workout #fitness #muscle #bodybuilding #motivation #biceps #lifestyle #sweat
