hi guys, quick questions.
with the two types of bridges - where your back is to the floor (reverse bridge) and the other where your stomach is to the floor, are they both working the back of the neck primarily?
i can do the first 4 progressions in this vid-
and i can arch my back up and hold it in no.5 (reverse bridge), but in comparission the the guys foot placement in the normal bridge, mine are further out, so i have less of a V shape. is this ok?
