Pick up something heavy from the ground and press it over your head. Once is all that is required. Post video and give known or estimated weight.
Has to come off the ground.
Arms need to be straight (not necessarily locked out) at top.
It is a press, not a jerk. Push presses are perfectly fine.
Use whatever equipment you want. Barbells, dumbbells, pressing logs, kettle bells, etc. Even tires, fallen trees, sand bags, or a friend or two are fair game - whatever you are comfortable lifting or willing to try to lift over your head.
Use whatever technique you want as long as it is a press in the end.
Note: Power cleans are easy enough to learn. There are articles on the site that explain them well.
