1) Try one-arm bent-over dumbbell rows instead of bent-over barbell rows. I think you’ll find that it’s easier to maintain correct form as you increase the weight you're using with a dumbbell instead of a barbell. You’ll also put less strain on your lower back, and if you're deadlifting like you should be, your lower back is getting plenty of work as it is. Not an original idea of mine (I forget who suggested it to me, honestly), but I really like it.
5) It is hard to overstate how great pull-ups and their variants are for your upper back and arms. They’ve probably been my #1 source of upper back, bicep & forearm improvement. I know because I added them to my otherwise good program about 1 month late, and my back and arms immediately started to improve over and above what all my other working out was doing.
6) If you are interested in any of Chad Waterbury’s training programs, “sterno” from the Testosterone Nation forums has compiled all of them in one big spreadsheet with CW’s approval. He has also included all the links to the original articles, so you can read up on all the programs and choose the one that best suits your goals. It includes the popular “Big Boy Basics” weight program. It can be downloaded in Excel and Acrobat formats here.
