I might be taking some PEDs
But seriously, you may have a proficiency for them and not even know it yet, unless you're one of the very few I'd bet it starts getting ahead of your squat soon.
I did my first DL in prison in 2012, 245x3, I remember it well. There was this skinny dude that could do 405x3 and I couldn't imagine ever lifting that much. 405 was the biggest bar you could get, all the bars were pre loaded with plates and welded on from 95lbs to 405lbs. Carrying them to where you wanted to lift was fun as you can imagine. Only option for going heavier was tying dumbbells on with something. Anyway, most I ever got there was 315x3. I never enjoyed deadlifts while I was there though.
Fast forward to 2013 I was home on house arrest and only had those junk concrete weights. Biggest plate was smaller than a 25. I loaded the bar with everything I had and tied whatever extra I could and I figured it to be 275. I got to where I did this for sets of 10 every week.
Five months later I got a gym membership and pulled 335x3 the first day. Around a month later I pulled 405x1 for the first time. I was really into deadlifting at this point. Six months later I pulled my first 500x1. Funny to watch the videos now because I was so skinny and my form sucked. It was around six more months later I pulled 555 at a meet. Took another year to get 600.
Anyway, that's my cool story for the day. The point was I didn't really make hardly any progress until I figured out what worked for me and then it came really fast. You may find your groove and add 100lbs in a few months. It's 100% possible.
