Dumbells in the past were never my first choice of weight resistance equipment. I always thought and really felt you needed to use the barbell to perform the big multijoint compound exercises. After I was forced to use dumbells only because they were all i had to use, I changed my mind rather quickly. The first thing I found was that the joint discomfort I sometimes experienced with barbells was gone. I could adjust the weight I was lifting according to the specific joint that was being stressed. I also found through unilateral training I could bring up lagging or weak body parts by training them seperatley or by themselves. So right now dumbbell workouts are what I prefer to use. Dont get me wrong, barbells are awesome too, but dumbells are a great alternative to use by themselves.
