tonight I worked upto a max effort single on squats. I know weights above 90% generally tend to get ugly or are slow. I got my last lift and ironically my max spot on, form didnt break, un rack and walk out were smooth and I know you're probably thinking well thats not a true max then. Wrong, it was slow as hell finishing, wouldnt have had another 0.5 of a kilo believe me.
I believe I have a problem with my upper back tightness as generally when im up around 90+ the bar tends to roll if im lazy, or my upper back lets me down. Ive worked hard last two training cycles at increasing mass up there but im starting to think maybe taking a different approach in isometrically training my abs/and upper back/thoracic region. The only other way I can think of helping myself out is practicing unracking heavy weights so reverse band squats and or heavy walkouts, possibly high rep SSB seated GM's, in a thoracic extention sort of movement.
Also, I know I have ways to go in just getting plain stronger everywhere (500lbs) but im keen to hear some of you really strong guys suggestions and if you've seen and conquered this before yourselfs.
