Meh, I'd suggest John Brown's series at Ringside or Title Boxing's series(Jeff Fenech, few other great trainers).
John Brown's are very informative but it's just his training, Title's includes sport trainers, experience cornermen, fighters, coaches, etc.
The Title ones are the most complete in my opinion. From training routines, to hitting the bag, to working a corner, to exercises with medicine balls.
Of course nothing should be substituted for live training with an experienced trainer, but if you absolutely have no other choice than to learn from scratch.......Go with Title's.
