I alternate mixed grip for a couple of sets until I get to the last working sets. I always have. I think it was an old habit from back in the day someone old head taught me.
I do this too. Sometimes when you’re pyramiding the weight up you need to count so you’ll get the dominant grip on to your heaviest set 😊
Definetele makes your upperbody unbalanced if you always use the same grip.
Wes had a solid point about the cottage cheese glutes at the top.
Lots of people, like Brian here in the vid, do not complete the lift. Bar stays a little low on the upper thighs and chest/belly is just pushed forward to make it look like full extension.
[edit.] Kranks pic above is just what I mean. Thats perfect 👍
