I am currently on HS1/PE2>iM and I've still got a long way to go. I realize that I may have been progressing the wrong way. Should I:
1) place hands at width that allows arms a full 90* ROM (keeping the chest up). Over time, slowly work hands closer together until shoulder width.
2) Place hands at shoulder width and raise arms to end of current ROM. Over time, achieve 90* ROM in shoulder angle but always keep hands at shoulder width.
I had been doing #2 because it seemed easier to gauge progress this way, but progress has been a little slow. For the past two weeks I've tried doing #1 and have found that it is a) much harder and b) I was right that it is harder to gauge progress.
