Here is a quote I read on the internets today, so it must be true :P . I am wondering if this is something I should be concerned about while doing SF
One final note I should make is that the amount of chins you do should be evened out with an equal amount of rowing motion exercises (face pulls, band pull aparts, inverted rows, etc.) for the upper back.
If you don’t do that you could end up with internally rotated shoulders and a host of other problems you’d want to avoid.
