Hello, today I used my thick Spud Inc belt during squats and deadlifts. Squatting with it felt pretty intuitive and normal, but it made my deadlifts feel awkward, like I couldnt use the movement pattern I typically use or something. I actually rocked forward onto the balls of my feet and had my heels come off the ground for a quick moment, so I decided to back off the belted deadlifts and examine things closer.
Is this difficulty revealing some sort of problem with my deadlift form? Maybe I am used to rounding my back at the bottom of the lift, and the belt is preventing this mistake, thus throwing me out of my habituated pattern? Im pretty sure the belt I bought was in fact marketed as a deadlift belt, so it seems odd that it felt good on squats but so awkward during deads.
But at the same time, elitefts.com sells a belt that is half as thick as thier normal belt, and the website says that being thinner makes it better for deadlifts. This Spud inc belt I have is very thick and just seemed to be getting in the way/preventing me from moving through the range of motion im accustomed to, as mentioned above.
So in short, my question: Is my deadlift wrong or is the belt wrong for me?
