Breast Workout Plan

This is how to do it

Grab a dumbbell in each hand, and step one foot backward so your feet are staggered and your toes are facing forward.
Bend both knees. With your elbows slightly bent, open your arms out to the sides so your palms face forward and the dumbbells are just above shoulder-height.
Punch your right fist forward and slightly left so it's in line with the center of your chest, turning your right palm down as you swing.
Bring the right fist back to starting position, and punch forward and slightly right with your left fist.
Bring the left fist back to starting position to complete one rep.
