Dude...no offence...but you only squat 231 and you've been training for a while. I've only been squatting for a few months and I could probably hit 315 for a single back squat right now and 235 for front squats. For gaining muscle 1 time a week may be enough but for strength 2x a week a week at 17 years old will produce much faster results.
Additionally, I think it would be perfect for him to front squat 1x per week and back squat 1x. Tons of peopel do that and have great results. Jd, since you are mainly focusing on strength you could do 3x5 front squat, and 3x5 back squats with a few days rest in between. After a week if you are still feeling sore or too tired form all the leg work, drop the front squats.
I could critisize your strength too, i looked on the last page of your log on the first workout i saw and:
135x8 strict rows? Compared to your 255 bench bro this is way too low and shows an inbalance
160x8 curl grip pulldown? this is pretty weak compared to your deadlift and bench aswell
125x5 OHP this is way off too, I press 121x3 overhead and I only bench 193, and as you pointed out I only squat 231.
Besides, your 17 and Im 15, your way bigger than me at 180 10%bf when Im 175ish 18%bf. And Iv had 3 big injuries this year which have stopped me squatting for weeks on end and put my numbers back, squatting has been very frustrating.
from what is said in your log, your diet isnt that good either, and you take lots of supps to makeup from it, I might be wrong about this though.
see anyone can critisize eachother's lifts, and Im sure not many people are 100% happy with all their lifts either, my squat is way weaker than where is should be and doesnt compare to my deadlift.
but you are right about front squats being a good assistance for squats
