Note: Used Rx'd weight for women. This was a battle. Got through the first round unbroken. Did sets of 10 for the 75 pound snatch and sets of 6 for the 100 pound snatch. Last 100 pound snatch was completed with :10 to spare -- had nothing in me to throw on the 10 pound plates and try for 1 or 2 more reps.
