Thats a good idea. is that 100kg snatch and 120kg clean and jerk? if so that is still an impressive weight to move. especialy if you were learning by yourself.
I do have a video of me doing some overhead squats with some pathetic weight. my form is better now and I can use more weight.
I was doing these just to get more confident under the bar. Don't like the idea of dropping it on myself if i try and catch it in a full squat haha. But I found they have a great carry over to back squats and they're great fun to do.
So just doing empty bar work etc for a warm up and gradualy adding weight would be a good way to go? My gym would not be very happy if I dropped the bar.
I'll try and get some videos up.
