Thanks for the advice (the Westside links were really helpful). I think my normal routine, plus chain use and rack lockouts, ought to give me 20+ pounds on my last bench max. I'm using the chains for squats and deads, too. By the way, Arnold Jr., I'm not looking to improve my physique, I just want to give it a try to see if it helps me work through my sticking points. I'll post a follow-up after about 6 weeks.
