I looked at it like a bent row to my belt then driving the hips through, holding my breath from gripping the log till it is racked then taking a breath before the press....this is probably not the best method as by the 5th C&P I am out of breath but this is a HARD drill...in a way it is three moves up and two down so it is complex and IMO harder that DL or squat reps.
I am just doing strict presses now as I am in a confined space and not sure what woould happen if I fell backwards or lost the log behind me which could happen if I moved up to weights I could jerk.
After an accident I damaged my ulnar nerve and I thought I was done with lifting a straight bar BUT going thumbless the nerve does not "pop" so maybe I should stick to a barbell.
I went out in the garage and tried lapping the log, yea, it is a lot stronger that way...I always have that nasty bruises on my forearms too.
