I wasn't sure if I should post in my other thread, or make a new one since the topic is slightly different, I decided to make a new thread. Anyway, I tried sumo deadlifts today and they felt way better and more natural for me. I'm sure this is probably due to some sort of tightness. I've been having issues with my SI joint. I went to PT about it and they gave me stretches to do, the pain went away for awhile, but not it's coming back again. My conventional deadlift form is good, atleast I think so. However once the weight gets heavy, I feel all this tightness in my lower back and around my hips. I do a lot of stretches, but still the same issue. With sumo deadlifts atleast so far, I don't have that issue. Would it just be better for me to switch to sumo deadlifts, atleast for afew months? Also for whatever reason, when I do deadlifts my body gets really hot, way more so then when I do any other exercise. It's 36 degrees out, the heat is off and yet I still had to open the windows when I was deadlifting. Any advise would be great, thanks.
