I just cant do these at all though Gironda and a few others have mentioned they are the best upper back exercise. I was wondering though they are quite similar to just standard bent over barbel rows ( that is if you use your imagination and think in pure bodily movement not configuration ) and I can do these. Should I just do barbel rows instead? or atleast until I have the strength to manage sternum chins?
How do you do your “ordinary” chins? Try to do them for a while so that you squeeze them to the end. Touch the bar with upper chest, this shouldn’t be too hard. From there IMO it’s easier to progress to touching the sternum.
Have you read this?
