I have been doing a variation of Madcow's 5x5 for the last couple of months. But now my back is giving me troubles again. After unpacking my Biotest package (the irony!) my lower back has started to feel funny again (some bulging disks I guess). My suspicion is that my deadlift form got out of control again and the stress on my lower back has started to get too high. So I have decided to stop the 5x5 and DLs for a while and try something new.
I am thinking about trying HSS-100 ( http://www.T-Nation.com/free_online_article/sports_body_training_performance/most_powerful_program_ever ). I am also thinking about trying Doggcrapp again which I ditched for the 5x5 because I was told at IM that I am not advanced enough. But I have to say my muscle gains with the 5x5 were at best slightly better than those with DC. Any opinions on HSS-100 vs DC as hypertrophy programs for an intermediate 35 year old lifter? Or suggestions for hypertrophy programs that would be more suitable?
