Thanks. My problem is that I can't do the proper rack position. I'm using my wrists wayyy too much partly because I don't have enough shoulder mass to hold the bar.
I have the same problem. I haven't done actual power cleans yet, but I've been practicing the rack position. It feels awkward and wrong. I feel too inflexible to bend my arms in such a way, where it's only on my shoulders and not on my wrists at all. Plus it also just hurts having it on my shoulders.
