I've started to perform the Clean from a month, and I often have an issue: when I try to catch the bar, it lands on my upper chest instead on my collarbone.
The following picture shows the point where the bar touches me when I try to catch it (in red). I do not do this mistake every time, but when I do it I instinctively stay for a while in a sort of isometric contraction (about 1/2 second) desperately trying to bring the bar to my collarbone for the rack position. When it happens, I probably use my arms and I feel pain in the blue points in the following picture.
To make it clear, I've uploaded a video there.
My Opinion: possible causes are
My legs aren't able to pull the bar high enough to get under it. However, sometimes this problem occurs also with a light weight (despite less frequently)
I'm not fast enough to get under the bar. From my video I think I'm not able to go under the bar. However, I think this can't be the only mistake. In fact, as far as I'm concerned, the Muscle Clean exercise allows the athlete not to go under the bar. So, even if the purpose was to make a normal clean, this technique is not inherently harmful. But I feel pain in the blue points, so there is probably a mistake I cannot understand.
My elbows are not quick at raising up
What do you think is the cause and do you have any suggestions to fix it?
