Hang power cleans are pretty cool. That woman is doing them with the bare bar, which is 20kg (44#). I did them yesterday at 95#, working on pure form. I also did some straight power cleans, starting from the deadlift position. Lots of jargon there, huh?
"Clean" is the ending position: bar at shoulder level.
"Hang" means starting with the bar held mid-thigh.
"Power" means you don't drop under the bar to receive it; your hip drive must be enough to send it up to your shoulders.
In the full clean, sometimes called a "squat clean", you drop down under the bar to catch it, then stand up. The last vid link shows a guy doing them instead of a woman, but he explains it really well.
And that's one of the things I do at the gym these days. My goal is to do Crossfit Linda some day. Yes, that woman is very fit, but she still struggles with the bench press. 120# was probably too ambitious for her. It's cool to watch her push through it and get them done anyway. Makes me believe I can get there too. Some day.
Random: Sharpie Liquid Pencil. Is erasable like pencil, then sets like ink after three days. Must try!
