Dude something that was simple that worked for me was focus on reps and gaining weight/size.
I waved through sets of 10, 8, 6, 4, 2, and 1 for 3 weeks each, starting my waves with more sets and gradually did less and less in a mini peak cycle and my squat went from 285 - 350. You just make it your goal to hit 10 lb PRs each week no matter what wave you are in. I would’ve squatted more but I back injury I got at work shot me in the foot.
And do high rep Deadlifts as well as upper back work twice a week to avoid that from it becoming a week point.
Also following the same idea; doing high rep pause squats didn’t hurt my progress that’s for sure. Just started at a 20 rep max and added 10 lbs and reps to the bar each week.
I personally didn’t do much hammy work during this program but I’m sure it will only help.
But I can’t say enough use reps. Remember you’re not moving much weight and your lacking in size so the reps will help build you a base and the more muscle you have it will only help you. Also remember, it’ll be more reps and lighter weights to help build and en grain your technique. Just try to do what the Lilliebridges do and separate each rep like they are each a single. Set up each time like you just walked it out and locked it into perfect position so you get max carryover when you peak.
Also one thing that will make a huge difference in your squat will be eating. The day before a squat day eat something salty like a pizza or a thick cheeseburger with some ice cream. Get a good bloat, because even if your progress stalls on the program, your bodyweight going up will keep your strength moving up anyway. And the day you squat hit it hard and leave no question you gave everything. Get in a good preworkout meal, try stimulants lol take in good carbs and protein in during (I’m not going to whore plazma even though it’s my favorite lol for me I tried just gatorade and bcaas but the sugar spikes were just too hard on my diabetes. Plazma no such issue ) and each like you want to grow from your session. Remember the better you recover the faster you grow.
Sorry if i wrote a book, but this one got away from me because squatting was a difficulty of mine too for years…
Hope this helps…rant over…
