I think I've figured out the problem I have with the deadlift and which resulted in pulling my back at my last max attempt (150kg) and a long break from back work. I seem to have a problem getting the bar off the ground. When the weight gets heavy, my hips shoot up first without moving the bar. The result is that my lower back gets a handfull all of a sudden and has to compensate. Once the bar is above the knees, the lockout is ridiculously easy. I've never had even the slightest problem with lockout. Getting the bar moving, on the other hand, is a huge issue. I figure the problem is the legs, and after spending a session trying to isolate the problem, I'm pretty sure it's the legs. They struggle to get the weight up, which leads to leaning over and overcompensating with my lower back, as I said. As an example, I last managed a set of 5 Zercher squats at 90kg. On the other hand, I deadlifted 130 for 5 around the same time (not today). So I figure I need to do more leg work to improve it? I switched to a westside for skinny bastards routine recently, and my lower body day consists of deadlifts, bulgarian squats and pull-throughs. Doing more than one leg/back intensive day is not a good idea because it doesn't jive well with my (mostly kicking) TKD training, making it hard to recover in time. Should I alternate deadlifts with a squat variant (no squat rack, but I can do Zerchers, front squats and the like)? Should I replace deadlifts with a squat variant and work really hard on deep squatting for a while till the legs catch up? Should I add a squat variant to the leg day before Bulgarian squats? I appreciate suggestions. Another thing. I feel a pull in my hip flexors when deadlifting (or squatting) heavy. I assume it has to be a result of tilting my pelvis forward and keeping my back arched. Should I strengthen my hip flexors? Stretch the glutes/hamstrings? Any advice?
