Thank you for the compliment and of course I don't mind at all
When I was about 18-19 I started training MMA 3-4x a week, I was pretty undersized. About 6'1" and 170lbs soaking wet. This kind of led me to transition to strength training even though I had no clue what I was doing. I kind of fell off the wagon during college, and then fucked around and joined the army in 2010. I deployed to Iraq in 2011 and began lifting more seriously, I was about 195lbs.
I basically followed my own program I guess you could say, a normal week would be squatting 2-3x a week, sometimes leg press and front squat. Lots of back work with dumbbells and pullups. Bench and OHP 1x a week. and Deadlift once a week. I usually was in a low rep range for about the first year of lifting. I deadlifted 500 the first time after training about 8-9 months, my bodyweight was up to around 220.
After that I got a little more specialized, did mostly sheiko 29 and 37, and ran 531 for about 6 months or so. I think the best progress I made was just from frequency, I started benching 2x a week and deadlifting on my squat days as assistance. I did my first powerlifting meet in 2013 @242 (though I weighed about 235) I hit a pretty shitty squat of 440, benched 344, and hit a 623 deadlift. So this was after about 2 solid years of training.
Currently my training resembles the cube mostly, as I alternate my deadlift and squat weeks (heavy/light). Also around this time last year (weighing about 250) I decided to move up in weight as I was still lean and having a large bone structure I didnt think 242 was my weightclass anymore. I'm now around 273 morning weight, remained as lean as I was last year and all my lifts have gone up, tested my maxes over winter at 600/405/700.
if I had to pick exercises that I believe helped my 3 lifts the most:
squat: heavy back raises, stiff leg DL
bench: seated BB OHP and weighted dips
DL: paused DL and front squat
Im gearing up for my first strongman event in June so my training is a little different now but I still have to deadlift 800lb before I can step away from powerlifting completely
Also I think the best advice I can give for beginners is to do a ton of back work, do upper back everyday you lift. It will pay off by giving you a thick set of lats, rear delts and traps. If people are concerned with looking like they lift this is a good place to start. My arms grew without ever doing arm work this way.
