yes, it was the only lifting I was doing.
push days looked like:
standing overhead press
front or half squat
flat bench or db floor press
pull days looked like:
weighted pullups and variations
each day was performed as 3 circuits with 8 reps per movement and as little rest as possible between movements, maybe 90 seconds rest max in between circuits. with every session, I always tried to increase weights, decrease rest periods, and/or increase explosiveness. my weights went up pretty much across the board, RDL in particular started at 155#, then 185#, then 205#.
my heart rate usually averaged around 150bpm and peaked around 170-180 bpm. the whole thing took maybe half an hour and I was WIPED OUT after, but some days I'd do another ten minutes or so of loaded carries or sled drags. my ITB really hated me after about ten weeks...
