These Soviet monsters show what a flat back looks like. Besides the fact that Ivanchenko’s back looks like something from a Marvel comic, I like the photo of Rigert the best. Ivanchenko is under load, but Rigert is on his way down to set up for his lift and his back is still perfectly in extension. Remember his photo the next time you set up for a lift, or pick up a kettlebell, or your bag, or kid, or pull anything up. And, you have got to admit, Rigert’s striped lifting shirt is pretty sweet.
