I have been doing the below workout for the past 5 weeks with good results. I just want to make sure I'm not missing anything and that I'm doing enough sets?

Day 1:

Flat bench 3x6 (last set RP)
BO Rows 3x6 (last set RP)
Tricep bench dips
Rack Chins (last set RP)

Day 2:

Trap bar deadlift 1x6 (any more hurts my knees)
OHP w/squat combo 3x6 (using dumb bells)
EZ Bar curls 3x6
Reverse crunches
