I always heard that you were to be able to press out at least your body weight. Now, if that amount is for regular training or your max, I have no idea. I can press my weight and then a little more, but it's not spectacular
I've recently gotten back into the gym after a 3 month break. I didn't do too bad lifting 275 lbs. I'm trying to work my way back up to 300+. I think young to middle aged people should be able to lift their body weight 10 times. I shouldn't say anything because I can currently only lift my body weight 6 times, but I'll fix that in the coming months. Good overall physical condition is important when defending ones self.
