Does anyone else's lower back fatigue very easily? I seem to have a difficult time doing more than 3 sets of lower back work before the tightness/soreness makes it too difficult to continue.
Right now, I'm doing a 6-day/week program called Big Beyond Belief, and the phase I'm currently on calls for one back and one leg exercise every day. I've set things up to where I'm doing a back width exercise and quad-dominant exercise on M/W/F and a back thickness exercise and hamstring-dominant exercise on Tu/Th/Sa.
Today, I did 3 sets of corner rows (back thickness) and 3 sets of straight-legged deadlifts (hamstring-dominant). However, after my 1st deadlift set, my lower back got so tight that I had to drop the weight and take a longer break than prescribed. I couldn't even finish my third set due to the tightness/discomfort.
Am I just being a bitch, or is there a greater issue here that I should resolve ASAP? For what it's worth, the deadlifts are my only hamstring-dominant exercise that recruits the lower back, so today's exercise selection is the only one that really sucks. Should I just throw out the deadlifts and replace them with another hamstring isolation movement? My other two hamstring exercises are glute-ham raises and lying leg curls.
Any advice/suggestions would be greatly appreciated. Thanks!
