All right folks here we go, because there is so much material
to cover on this subject I have decided to break it up into two parts. Today we
will be talking about corrective mobility exercises that can be utilized to
combat some of the effects of sitting all day. Sitting in that smart car for 15
hours over the course of a weekend really started to get me thinking. The
average person with a desk job who isn't very active probably sits this much
EVERY day at least 5 days per week. Let’s say an hour commute to the office, 8
hours of sitting, an hour home, and 4-5 more hours of eating dinner/watching
TV. Sitting this much not only affects the musculoskeletal system, but has also
been linked to more serious diseases like cancer and diabetes. I think the
picture below, not that I'm an evolution advocate, accurately depicts one of
the two paths modern humans are likely to go down- if not both…
So what are we suppose to do about this sitting epidemic
outside of "don't sit as
much"? Before I answer that question I'd like to make a few basic
suggestions. I usually tell people to get up at least every hour and walk
around, stretch tight affected areas and do a few burpees (just kidding). If
it's absolutely not an option for you to get up that often you need to make
sure you’re in the most ergonomically/biomechanically correct position
possible. I should note that this should be done anyway regardless if you can
take a walk every hour or not. Achieving this position can be done through
various back support devices, ergonomically designed chairs, proper desk
height, and most importantly awareness of your position. Pictured below is an
optimal ergonomically correct sitting position.
So having a clear understanding of how you should be sitting
(when you have too) and knowing how you actually sit let's talk about some
corrective exercise strategies. I am going to keep this pretty simple so that
it will be of utility to you right away. Taking a top down approach lets first
discuss the cervical and thoracic spine (neck and upper back). I'm not going to
discuss any cervical spine exercises today but it is important to pay attention
to your position here. We don't want any forward head posture that's going to
excessively recruit the upper traps and cervical flexors/rotators. This can
lead to a ton of neck pain and discomfort. I use a simple cue in the gym that
can be applied here to correct this, "Make a double chin." This
successfully "packs" your neck into a more neutral position putting
less strain on the neck muscles.
Moving to the thoracic spine if you think about the position
you sit in all day your upper back is pretty hunched over (flexed). Spend
enough time in flexion, oh say 15 hours a day and there will be some carry over
of that position into your normal standing posture (hunchback). The problem
with being stuck in this position is that it affects the force couple with the
shoulder girdle. When this relationship is screwed up it can affect scapular
movements such as upward rotation resulting in subacromial shoulder impingement
and several other pathologies. The good news is the t-spine can be easily
mobilized and stretched in both extension and rotation with a couple simple
exercises using a foam roller.
Starting position:
The first exercise mobilizes the thoracic spine into extension. You're going to set up with the foam
roller right in the middle of your upper back. Support your head and neck with
your hands and interlace your fingers, with your elbows close to your ears
pointing up towards the sky.
Finishing position:
From here, I am going to brace my core (tighten the core) to
"tack my ribcage" down and extend backwards on the foam roller. I usually hold the extended position for
1-3 seconds and come back up. It's very important to do this slowly and not to
allow your ribcage to flare up. If it does you’re moving through your lumbar
spine and not your thoracic spine, which is NO BUENO! You can roll to different
segments of your t-spine to mobilize but DO NOT try to do this on your lumbar
spine (low back).
The second t-spine mobility exercise works to improve
rotational mobility. This is extremely important for many overhead athletes,
especially swimmers.
To start, lie on your side and flex your top knee to 90
degrees. Slide a foam roller underneath the flexed knee that runs parallel with
your body. Next, make sure your hips are stacked and body is in one line.
Extend your arms out in front of you and put one hand on the other like you are
giving yourself a high-five.
To initiate movement brace your core, keep your knee on the
roller, and rotate back as far as you can with your top arm only. Do NOT allow
any rotation to occur through your lumbar spine (lower back), all the movement
should come from your upper back. Also, do not push past any restrictions you
feel as you go back. I usually do 2 sets of 6 reps per side for this exercise;
you can do more as needed.
Moving anterior (forward) to the t-spine lets address the
pectorals (chest) or more specifically the pectorals minor. Just as the t-spine
gets stiff in that flexed posture we sit in, the chest muscles becomes short
and stiff. Once again, spend
enough time in this position and there will be some plasticity. Pectoral
tightness pulls the shoulder girdle into protraction (rounded shoulders/hunchback).
The bigger problem is the pectoralis minor as it tips the scapula forward when
it’s tight. This accompanied with serratus anterior weakness makes for a very
unstable shoulder position that is very prone to injury especially in
overhead/throwing populations. Here is a simple stretch you can do to stretch
the pectoral muscles while also engaging your glutes and core.
To start you need to choose the correct stability ball for
you. Sitting on the ball your knees and hips should be flexed at 90 degrees.
Once you have chosen the right ball roll out into a bridge position from the
sitting position. Engage your core and glutes but don't arch your back. From
this position outstretch your arms to your sides, bring your hands slightly
above the shoulder. Having the hands above the shoulder ensures you are
stretching the pectoralis minor and not just the shoulder capsule. I do 2 sets
of this exercise with 30-second holds; you can do longer if necessary.
Lastly let’s discuss the hips, I am only going to attack the
hip flexors today but it should be noted there are a lot of other areas that usually
need attention. The dysfunction to this area resulting in sitting usually
causes the most discomfort. Just like with the other tissues if you spend
enough time in hip flexion those muscles will shorten. This shortening will
carry over in normal standing posture and every other movement as well. When
the hip flexors become tight they pull the pelvis into what we call anterior
pelvic tilt. This in turn puts a lot of pressure on the lower back and forces
us to move through the lumbar spine to get range of motion (ROM) in many
activities.
There are several muscles that can initiate hip flexion but
the llippsoas and rectus femoris (one of your quad muscles) do most of the
work. In order to correct this spine posture we need to mobilize the shortened
tissues, then lengthen them with stretches, and strengthen the antagonist
muscle group (the glutes). I am just going to go over the stretches today to
give you something to use right away.
Both of these stretches are pretty aggressive, you may need
to modify the first one and or skip the second one if you are really tight. For
the first stretch start in a half kneeling position, squeeze your glutes and
roll your hips under you (like your going to hump something). This will bring
your pelvis into a posterior pelvic tilt and put a stretch on those hip
flexors. If that feels easy, then you can elevate your back foot. Start with a medicine
ball to elevate your foot and work your way up with aerobic steps until your
using a plyo box like the one pictured. You may also want to use a dowel or
foam roll while you’re in this position as a balance aide. Its very important
to do the hip tuck otherwise you will not get the effect of the stretch and are
probably moving through your lumbar spine.
The second stretch commonly called "spiderman" is
initiated from a lunge. Step into a forward lunge and sink your hip down
towards the ground. Put one hand
on the foot that’s in front and the other on the ground directly under the
shoulder. If this position is too intense you can set your knee down to take
off some tension. I like to oscillate in this position and search around for
tight spots. I usually do this stretch as part of my dynamic warm up; I do 10
reps total holding for 1-3 seconds in the bottom position.
