I may just be really stupid, but is there an easier way to do dumbell bench than just leaning back and beginning my set? I am starting to train real heavy (for me) and every time I go down to start my first rep, my should gets real sore. It usually takes a day or two to recoup, but it screws my chest workout up every time I attempt this. Any suggestions on doing this exercise with dumbells or should I stick to the barbell all the time? I had been mixing it up pretty often.
