Yeah, tons of stuff, depending on the lift.
My flat progress dropped to a snails pace looong time ago, so it's probably the lift I get most exotic with in terms of experimentation. I mostly keep my progress going just by experimenting with different types of volume and by working on weak points in my lift... so, in other words, if my lockout is a weak point, I'll do tons of triceps work to bring my lift up.
Incline I still manage to find success just by resetting my weights and cycling my grips. Haven't had to use anything fancier but I could always do some paused presses, pin presses in a squat rack, etc etc. Also just started doing DBs so that will carryover quickly I'm sure.
Squat will plateau from time to time but it's nothing that a simple reset in volume, weight, or reps won't easily fix.
If any of these ideas appeal to you, please by all means use them, I'd love to see how others react. I will say that juice has definitely simplified the process for me... I haven't been doing anything but getting underneath the bar and pressing and yet I still see consistent progress, which is nice
