"Lower the bar quickly, but under control. Lowering a bar slowly will build muscle mass but not strength. Please, I beg you, stop reading bodybuilding magazines. They have contributed greatly to ruining strength training in the United States." Taken off of a westside-barbell.com article. I know that's how I've been lifting all this time because I'm always hearing "go slow on the concentric portion". Apparently that's just for bodybuilding. Anyone else do this already, or is this something that most of you already knew? Also, if you don't know about Westside, it's one of the most notorious powerlifting organizations around, with lifters achieving well over a 1000 pound squat, so this is definitely from a trusted source.
