What is more effective to work with? I try to use dumbells where possibly due to the greater amount of stabilizing muscles needed to control them. I can shift more weight with a barbell though so if I am aiming for maximal power is this not more effective? I also dont like the fact if I am doing 1 arm dumbell lifts such as a snatch, or clean and press and I am doing 3-4 reps then my body actually has to perform 6-8 reps in total as you need to do work both sides of the body equally. This means that my body/nervous system fatigues as it is working for a longer period of time. What do you prefer and why? what excercises are best performed with barbells? and which with dumbells?
