Sorry if this is really dumb question, but here it goes. I bench raw, with a thumbless grip, and I have very long arms. The 'touch spot' (the area of my body that the bar touches when benching) that works well for me is usually the tip top of my upper abs/lowest part of my chest. It seems lately, whenever I miss a rep, it's because I'm coming down, and touching about an inch or two too high on my chest when lowering the bar.
Obviously, concentrating on hitting that sweet spot helps, but it seems to be a consistent issue, especially as weight gets heavier. Is this a common issue, that may be pointing to weakness somewhere else?? Or is it simply a matter of practicing technique over a long enough period where hitting the correct spot is natural?? Thanks in advance for any replies.
