get the tightest, thickest knee and elbow sleeves you can find. there will be minimal learning curve and should give you enough help to get you to 850 right now.
some sports company used to advertise a tight compression shirt that might give you some help in the the bench. not much, but you dont need much.
if you really need a little more, buy a tight pair of spanx and wear them under you clothes. it probably gives more support than the first squat suits did.
