Fig. 5.10 Anatomy Trains rules would require
that the 'Y' of the iliotibial tract continue out and
around the body in spirals as in (A), but the
actuality of the Lateral Line is that it starts a
series of crisscrossing 'X's up the lateral aspect
of the trunk, essentially like shoelaces sewing the
front and back together via the sides (B).
(Reproduced with kind permission from
Benninghoff and Goerttler 1975.)
these series of 'X's (or diamonds, if you prefer) is to
create a mesh or net which contains each side of the
body as a whole - a bit like the old Chinese finger traps.
The resultant structure is a wide net of a line that con-
tains the lateral trunk from hip to ear (see Fig. 5.2).
Instead of following the same direction, then, let us
turn a sharp switchback from the PSIS on the most pos-
terior fibers of the internal oblique, which head upward
and forward to the lower ribs. Laid over this is the more
superficial track from the ASIS, consisting of the poste-
rior fibers of the external oblique, which go upward and
backward. The fibers of both these muscles are nearly
vertical along the lateral aspect of the trunk, but still
take an oblique direction so that they form an 'X' (Fig.
5.11). If you pinch your waist at the side, the fibers of
the external oblique, running up and back from the
ASIS, will be more superficial. Deep to this will be the
internal oblique, palpably running up and forward. This
myofascia can be worked individually in rotational pat-
terns, or collectively just to lift the ribs off the pelvis
(DVD ref: Lateral Line: 37:24-*1:00).
The iliac crest and waist
The upper edge of the iliac crest provides attachments
for the latissimus dorsi and the three layers of the
abdominal muscles. The outer two of these, the obliques,
form part of the LL, and are fascially continuous with
the ITT over the edge of the iliac crest (see Fig. 5.3). The
external oblique attaches to the outside edge of the iliac
crest, the internal oblique to the top of the iliac crest, and
the transversus abdominis (which is part of the Deep
Front Line) to the inside edge. Practitioners can affect
different layers by adjusting their pressure, angle, and
intent accordingly.
In terms of the LL, the iliac crest is a frequent site
of connective tissue accumulation, and 'cleaning' these
layers off the bone can be helpful in coaxing length from
the LL (DVD ref: Lateral Line, 30:50-35:38). Direction
matters here: in cases where the pelvis is in anterior tilt,
the tissue needs to be moved posteriorly; in cases of
posterior tilt, the inverse is true. In cases with neutral
pelvic tilt, tissue can be spread in either direction from
the midline (DVD ref: Lateral Line, 35:39-37:23).
When the rib cage is shifted posteriorly relative to the
pelvis, the lower lateral ribs move closer to the posterior
aspect of the iliac crest. In these cases, it is necessary to
focus more on the internal oblique part of this local 'X',
to lift the ribs superior and anterior. In the far rarer case
where these lower ribs move down and forward toward
the pelvis, the external oblique would need to be
The rib cage
These abdominal obliques attach to the lower floating
and abdominal ribs. We can move up from here using
both the ribs themselves and the muscles between them.
The lateral aspect of the rib cage is likewise crisscrossed
with a similar pattern of myofasciae: the external inter-
costals running backward and up, the internal intercos-
tals running forward and up. These muscles continue
the same pattern all the way up the rib cage, under the
overlying shoulder girdle and its associated muscles, up
to the first ribs at the bottom of the neck (see Fig.
Although the intercostals follow the same pattern as
the obliques, they are much shorter, being interspersed
with ribs, so they do not respond in the same manner.
The fascia over the ribs can be stretched or moved with
broad sweeps. The intercostals can be affected some-
what by a fingertip inserted between the ribs from the
