Please advise some back exercises for back thickness?
Check the FAQ first if you haven’t already. There are many links to back articles there with pics. Just click on “Frequently Asked Questions” on the main T-mag page. There’s one article my Poliquin “Top Back Exercises” or something like that. Very good.
For back thickness I like snatch grip deadlifts, scapular retraction barbell row, partial barbell row (from mid-range to completion) and chins.
