Depends on the deadlift.
For a standard conventional deadlift, I like to reset every rep. I had a back injury that was pretty damn debilitating, and I completely chock conventional deadlifts with reset as the reason it’s so much better. If it’s not broke and all that.
Paused deadlifts on the other hand, I like TNG. I get more reps out, mainly due to my grip. While it’s not weak, if I reset on every rep my hands feel like they’re on the verge of locking up and it messes up my grip throughout the set.
I think it’s like squats though. There isn’t one method that’s right. Pick a way thats the most comfortable to you, with in reason, that doesn’t cause injury, and nets you strength.
