i have been lifting seriously for around 6 years and deadlifts are, easily, the most satisfying weight lifting exercise i do. its so simplistic-just you, the bar, and the weights. nothing else. i just started doing them about a year ago and in that year i have had more lower back development than the previous four years combined. whats even better is that deadlifts have pretty much cured the whole reason i avoided doing deadlifts in the first place-a bad lower back. now i have this fucking steel cage around my spine and i feel more solid than ever.
