I did day two of the Atkins induction yesterday. I suspect I might not be being quite strict enough: I will cut out nuts, half & half, broccoli, and anything vaguely suspect. I'll stick to animal protein, salad and other greens, avocado, olive oil, cheese, cream and butter.
I did Fran yesterday on very few carbs, certainly less than 30 g per day for the first two days. 7:18, a bit off my previous two (6:20,6:39) but not a disaster. It's going to be a struggle to get it down to 5:30 by September, but if this works, better body composition should go a long way to making the pull-ups faster. I could have gone faster, but I had a CrossFit Class to teach and did not want to be an utter mess.
