Low-back
pain (LBP) is
the single
leading cause of disability worldwide, with 619 million people affected
globally. In fact, most people experience LBP at least once in their life.
Fortunately, it is also the condition for which the greatest number of people
may benefit from
rehabilitation. While many conditions can lead to LBP,
inadequate core strength is often a contributing factor.
Increased sedentary
jobs and sitting time can lead to muscle imbalances and weak core musculature,
putting the low back at increased risk of injury. Here are
a few common reasons increased sitting time leads to LBP:
·
The deep core muscles
are meant to endure prolonged activation to support and stabilize the spine. When
we slouch in a chair all day, the core remains relatively inactive. This results in a decreased signal from the
brain to the core telling it to “turn on” and protect the spine when necessary.
·
The psoas major, one of
the strongest hip flexors, originates at the lumbar spine. Sitting can shorten
this muscle, putting chronic stress on the low back.
·
The gluteal muscles,
which are powerful hip extensors, become lengthened and weak—a condition known
as “glute amnesia.” These muscles are then unable to do their job in regular
activities of daily living, forcing other muscles, including those
in the low back, to compensate.
While avoiding sitting
altogether is unrealistic, specific exercises can help counteract the
effects of prolonged sitting and minimize your chance of developing LBP.
Here are four effective body-weight exercises
you can do anywhere to ward off LBP.
Plank
Tried and true, nothing enhances core stability like a plank. Start with your elbows positioned directly below your shoulders and the legs extended so that the body is in a straight line. Engage the quads, glutes and core, while pushing the floor away through the toes and forearms. Hold for 30 to 60 seconds, or for as long as you can maintain proper form, and repeat three times.
Ramp It Up: To
increase the challenge, find an unstable surface. This can be done by placing
the forearms or feet on a soft pad or exercise ball, or by raising one arm or
leg. Your hips and shoulders should remain in line with one another throughout.
Pare It Down: Decrease
the challenge by positioning the hands or forearms on a bench, table or
railing at a height that is challenging but allows for maintenance of proper
form.
Side
Plank
While the standard
plank is helpful for reducing the risk of LBP, the side plank may be even more
beneficial because it requires activation of the internal and external
obliques. It’s imperative
to strengthen these muscles, as they help control rotational movements of the
spine. Start with your elbow positioned directly below your shoulder. With the
feet stacked or staggered, drive up through the lower obliques until the body
is in a straight line. Keep the shoulders and hips stacked. Hold for 30 to 60 seconds, or for as long as you
can maintain proper form, and repeat
three times.
Pare It Down: Drop a knee to the
floor for additional support
or find an elevated surface on which to place the elbow and forearm, reducing the challenge on the core.
Glute
Bridge
Weak gluteal muscles
contribute to LBP by passing their work to the low back. The powerful
gluteal muscles support activities like walking, running, squatting and
deadlifting, but when they lack sufficient strength, the back bears the
brunt of the load. Start in a sit-up position with your arms
down by your sides. Press firmly through your feet and engage your glutes to lift up the
hips, creating a straight line from the heels to the shoulders. Hold for two
seconds and lower slowly. Perform one to three sets of 10 to 15 repetitions.
Ramp It Up: Increase the challenge
by performing this exercise with one foot lifting off the floor, while maintaining level
hips.
Bird
Dog
Begin in a quadruped
position with your core engaged. Slowly raise one arm and the opposite leg to
torso height. Your hips and shoulders should continue facing the floor. Slowly
lower and repeat for 10 to 15 repetitions or hold the top position for 15 to 30 seconds.
Repeat one to three times on each side.
Ramp It Up: Instead of the typical
flexion and extension seen with this move, try a lateral bird dog. Once you
reach the top position with the arm and leg extended, move both limbs a few inches
laterally. This will dramatically increase the core challenge. Slowly return to
the extended position and repeat for one to three sets of 10 to 15 repetitions.
Final Thoughts
Low-back pain is a
common and debilitating condition. With a proper routine, you can strengthen
your core and gluteal muscles and reduce your injury risk. This workout can be
performed with nothing but your body weight—at home, in the gym or at the office.
To further protect your low back, maintain an upright, engaged posture while on the
job and avoid staying in any one position for too long.
