been trying to reach 3 plates (i know its not a big deal but still)
im getting stucked at 2 plates and a half and i cant upgrade it yet (been 6 weeks im stuck there)
but i still manage to up my single arm db row and my tbar row
anyone has a good tip to up my deadlift?

What's your current deadlift routine? 275x5?

Stop trying to max every weeks...that eould be a good start. What is your routine?

Do work in the 80-85% range and up the sets.

deadlift routine
15x 135(warmup)
12x 185(warmup)
10x 225(working set)
8x 255 (working set)
Max amount of reps working set (275)

Is that what you do everytime you go in?

probably exhausting yourself before even getting to your working sets

you want the earlier lighter sets to be a warmup and to check form

could do like 135x5 all the way up to 255x5 then 275x5 a few times

Lol

Okay, that's a lot of volume for deadlifts when you're training for strength.

Read up on 5x5 or 531. I've been using a 3x8 program for my deadlift, which has been working well for me (DISCLAIMER IT MIGHT NOT WORK FOR OTHERS).
You may be exhausting yourself, as Qwaze said.

Progressive overload is key my friend.
Maybe cut your warm up in half (reps) and lower your working set reps, but increase the variability in weights.

Warm up - 135 x 8
1st set - 185 x 8
2nd set - 225 x 8
3rd set - 275 until failure or 8

Slowly build up your weight from there, adding 5lbs every 2 - 4 weeks.

Add 5 lbs every 4 weeks lmaooo

Remember the last guy who shoved 531 down hnf's throat?
