When doing a (standing, overhead) press as described in Starting Strength, are your elbows supposed to stay in a vertical plane, under your hands and in front of your hands (more or less), staying at the same distance from each other as you press the bar up? Or should they travel out, away from each other some, during the movement?
When I do it, my elbows tend to flare out some. I think this changes the muscle recruitment in the exercise. I'm not sure if this is a form error that I should correct (reducing the weight if needed), or if I should just ignore it.
I didn't see this fully addressed in Starting Strength, but I may have missed it. Rippetoe talks at length about a proper vertical bar path, and all the photos of people doing the lifts are profile shots, never straight on.
Thanks.
