Hunk said:Remember that when you're searching for your 1RM you're working to your limits, so remember to get a spot.
With your back squat there is quite a bit of variance for where you can place your hands. Just find a position that is natural and comfortable for you. Once you have found this position focus on on keeping them relaxed. Don't try to push your elbows up or down. It doesn't matter.
What matters is keeping your chest big and keeping the weight on your heels. Don't let your chest drop, otherwise you'll hips will rise up and you'll lose drive.
Focus on pushing your hips forward and through and not 'up'.
Hope this helps.
I had good hip drive and my hips fell below my knee, it was just this problem with flexibility that seemed to put pressure on my front delt and top of bicep, gripped as wide as I could anarl
