The Dorian routine is one of the best in my opinion, good luck.
As for the what to do instead question:
Nautilus curls -
Dumbell concentration curls
Hammer Strength pulldowns -
Close grip pulldowns
Hammer Strength one-arm rows -
Dumbell rows
Hammer Strength rear-delt machine -
Bent over laterals or cable laterals
Hammer Strength seated bench presses -
Bench press with very slight incline
Hope this helps
As said watch the "Blood and Guts" video
