Yap. I somehow miss the time before I got involved with all the lifting info. The only exercises I knew were bench press, bench pull, pull ups, push downs, upricht rows, curls, leg press, V-sit ups, lateral raises and bo-laterals. Thats a strange mixture I know. I also only knew rep ranges from 10-12 or 25-30 and figured out myself that its best to mix it up from time to time to make progress. I never trained in a public gym. But still sometimes people that trained as well would come up with some advice from some magazines and stuff like that. I ignored them because I was just better than they were and I prefered to play arround with the weights with my friends to find new exercises and new ways of exercising on our own.
On the other side I dont think that we would have invented something like apowerclean on our own ;D.
