Exercise Advice: This is virtually the same exercise as
the dumbbell biceps curls except that you keep your wrists in a
locked position throughout the movement with no supination. You
can perform this exercise by either standing or sitting on a bench,
whichever you prefer. Grab a dumbbell in each hand and let arm each
hang at your sides. Slowly curl the dumbbells simultaneously trying
to touch them to your shoulders. While you are performing the movement,
keep your wrists locked. Be sure to squeeze your biceps for a one-count
at the top of the movement. Slowly lower the dumbbell to the start
position and repeat.
