Stand with a dumbbell in each hand at arm’s length and the palms facing backward. Curl the weights up in front of yourself while keeping the elbows relatively close to your sides, then lower under control.
 
Purpose
The dumbbell reverse curl is a simple exercise for the forearms and biceps, and to help strengthen and stabilize the elbow. Using dumbbells helps achieve or preserve symmetry between the two sides, and also allows the hand and wrist to be in a comfortable position and prevents potential strain at elbows common when curling on a barbell.
 
Programming
Generally sets of 8-20 reps are appropriate.
