For a long while now I've been getting stiffness in my lower back, and this is normally the next day and so forth after I've deadlifted. My back never hurts when I'm squatting or deadlifting, due to stretching of the glutes,hips and hams beforehand, but it's always really tight and somewhat painful for the next few days, making it hard to do anything work-related. Is this normal for all lifters?? .
Also Some times when I'm just walking around or making any sudden movement, my lower back will just tighten up out of nowhere which ends up slowing down my movement. Does this mean I'm getting a disc bulge?? I don't feel any strain on my lower back just stiffness that makes it hard to walk at times. I'm hoping someone can answer this because I'm afraid of deadlifting every single week so I've cut it down to every other week, so I don't develop any serious back problems. People who deadlift at my gym always use a belt when they're lifting for reps over the 3 plate range, should I start doing the same thing since I'm currently lifting beltless??
