Oly Day! Should be easy, just nail it like this guy. He weighs about 207 pounds here and he's snatching 385 pounds. Nice.
You may want to start a little lighter...
Start your warm up with one set of two reps with a light weight, then start adding small percentages until you've done five or so sets, looking like: 2-1-1-1-1. Go heavy on your singles, push your PR up, or get a better idea (safely) of where it is exactly.
