i have always done upright rows as part of my routines. They never have had a negative effect on my shoulders. I generally keep the weight slightly low when i perform them. I still like to power clean every now and then so the upright rows help keep my shoulders flexible.
Great articles but those articles are the type of thing im talking about. I have read just as compelling articles about the value of NO2. However wether im right or wrong in the end, i dont think paying 40 dollars for the placebo effect is that bad. If taking something worthless increases my mental capacity to increase the work i can do then its worth it.
