When I deadlift heavy, lets say over 85% of my max, I find it really overproportionally taxing on my back. I undershoot my predicted max by like 10% or so and my glutes and hams are not even phased, making me feel like I am doing something wrong.
Im thinking that
- My form breaks down and I lift less from my hips
- My low back is the weak point in my lift and I need to bring it up
Does this make sense?
I really like training in the 75% range to “dominate” the weight as CT calls it and have good form and tire out my glutes first, but any heavy lifting I have something holding me back from getting close to my predicted one rep max and what I ~feel~ I can do.
Is the solution to start doing hyperextentions or some kind of focus on form? Im no beast but my predicted 1RM is 330+ and after working up to 295 in singles my low back is shot. Any analysis is appreciated.
