Struggling to reel in that undercling? You may want to work on those elbow flexors! Here are five exercises to strengthen your biceps and your brachialis. Aim for three sets of eight to 12 reps, but don’t do all the exercises in one sitting.

Bicep Curl

Stand shoulder-width apart with dumbbells in your hands. Your palms should be facing forward and away from your body. Keeping your elbows close to your body, lift the dumbbell to your shoulder. You can lift the dumbbells one at a time or at the same time.

Concentrated Curl

For this exercise, you can sit on a chair or an exercise ball. Place a dumbbell in one hand and place that elbow on your inner thigh, near your knee. Lift the dumbbell to your shoulder.

Reverse Curl

Stand shoulder-width apart with dumbbells in your hands. Your palms should be facing your body (the opposite of the bicep curl). Keeping your elbows close to your body, lift the dumbbell to your shoulder. Make sure to keep your wrist straight during the entire exercise.

Hammer Curl

Stand shoulder-width apart. Your palms should be facing each other, as if you are holding hammers. Keeping your elbow close to your body, lift the dumbbell to your shoulder.

Cross-Body Hammer Curl

Stand shoulder-width apart. Your palms should be facing each other, as if you are holding hammers (just like the hammer curl). Lift the dumbbell so it crosses your body and goes to your chest.
