Okay so I've been doing cleans for a while now ever since I started playing football for my school because they were part of the workout. The other day when I was at my gym however some guy in his early 40s came up to me after I finished my sets and asked me what i was doing. I told him power cleans to build explosiveness. He then told me about how he used to do them among other exercises and eventually the disks in his lower back snapped or something and his back has been bad ever since. He asked me if my back hurt after my sets and I said no because it didnt, and he said that his wouldnt hurt after sets either when he was young.

So should I stop doing power cleans because they are bad for my back?
