First workout re-vamp today: chest and back 3 exercise superset, 6 sets each, 15 reps per exercise - focus on lighter rates. Minimal rest between sets, in and out of gym in 35 minutes, perfect. I'm feeling it already. Legs and abs tomorrow unless I'm too sore. Also, I stopped the nightly pour of bourbon last night in advance of gearing up for this new routine (I love it, but that's the sacrifice). 5' 10", 170 lbs - I think I'd feel great at 160 lbs. Anyway, great start!

Great videos on you tube! I abandoned heavy weights when I started to experience back problems about 5 years ago... and am a believer that lighter weights with consistency and intensity produce better results. Specific question: open grip pulldowns, its that a lat exercise or a bicep exercise? Mike Mentzer videos say it was his preferred bicep exercise, but I don't know - it doesn't feel like I'm getting bicep isolation. Do I need to make technique adjustment to really hit the biceps?
